On today's call, we have Tom Rutledge, Chairman and CEO; and Chris Winfrey, our CFO. With that, let's turn the call over to Tom.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Thank you, Stefan. Despite the significant challenges that COVID-19 has posed, we've been able to operate our businesses throughout the pandemic. Earlier in the pandemic, we offered our customers a set of programs including our Remote Education Offer and Keep America Connected pledge that supported customers' needs, resulting in a significantly higher number of customers enjoying our services.
In addition, we opened our WiFi hotspots across our footprint for public use, opened up our Spectrum News websites to ensure people have access to high quality local news and information, rapidly connected and upgraded fiber services to healthcare providers and donated significant airtime to run public service announcements to our full footprint of 16 million video subscribers.
Our employees were given additional paid sick time for COVID-related illnesses and a flex time program to address other COVID issues. We also increased our wage for all hourly field operations and customer service call center employees by $1.50 an hour and we'll remain on path to a $20 minimum wage by 2022.
Our ability to operate our -- for our customers and communities despite the challenging environment is a testament to the quality of our insourced and onshore work force, our safety precautions, and in many cases, our ability to operate remotely. Our ads -- our sales and care agents have continued to sell our products and to provide outstanding service to our customers. Most of our stores have been able to remain open throughout the pandemic, serving customers in need. Our field operations personnel have handled professional installations and repairs, have continued their work in the field servicing customers in their homes and maintaining the quality of our physical plant.
Our plant construction has continued and we've actually seen plant miles and passing increase more this year than last. And our product development team has continued to develop and roll out various product improvements, including updates and enhancements to our video, internet and mobile products.
Our ability to continue to operate well under the circumstances is also the result of investments we've made in various parts of our business over the last several years, including our investments in systems integrations and automation, our self installation program, which ran at over 80% of installations during the quarter, our online and digital sales and self-service platforms and our network, including DOCSIS 3.1, which provided ample bandwidth to withstand surging use with Residential data usage for Internet-only customers remaining at an elevated 600 gigabytes per month during the third quarter.
Our operating and investment strategy has allowed us to sustain and accelerate our customer financial growth. During the quarter, we added 537,000 residential and small business Internet customers versus 380,000 in the prior year quarter. In the past 12 months, we've added $2.3 million Internet customers and $2 million overall customer relationships. We're growing well and gaining share against all our competitors in all of our markets regardless of competitive infrastructure.
In the third quarter, we grew our mobile lines by 363,000, 87,000 more than it had been in the third quarter of last year and continued acceleration from last quarter. We recently purchased 210 CBRS priority access licenses in 106 counties across all our key DMAs for just over $460 million. Over a multi-year period, we'll execute on our inside out strategy with small cells attached to our existing network using unlicensed and now our licensed spectrum based on the disciplined return on investment approach, consistent with our goal of reducing mobile operating costs.
Turning to the third quarter financials, we grew consolidated EBITDA by over 13% and our third quarter free cash flow grew by nearly 40% year-over-year. Looking forward and subject to what happens with the virus unemployment stimulus, we expect our broadband and mobile products to continue to drive demand and churn and growth to return to pre-pandemic levels. SMB has actually performed better than we expected and our ability to grow will also be partly tied to the economy.
In enterprise, retail sales activity is picking back up despite limited on-site access and those new sales get installed in the coming -- as those new sales get installed in coming months, we expect enterprise revenue growth to pick back up. Our advertising business is improving and our core ad business excluding political is about 90% back to normal, in part because of the amount of sporting events that are now airing.
So core ad sales are improving and we still expect political advertising to be meaningfully contribute -- a meaningful contributor in the fourth quarter. To maintain that growth, we'll continue to invest in our network, so that we can continue to offer new and better products than our competitors.
In the coming years we expect data usage per customer to continue to grow and we're prepared to deliver more throughput across our network. The growth in demand for data is and will be driven by a number of factors including the growth of IP video services, including video conferencing and gaming. Also the number of growing IP devices connected to our network, which is nearing 400 million devices. And new and emerging products and services are being developed as we speak, such as e-learning or telemedicine and 4K, virtual reality or holographic formats for examples.
We are continuously increasing the capacity in our core [Phonetic] and hubs and augmenting the network to improve its speed and performance. In the near-term, however, we have a large opportunity to improve throughput and latency by continuing to use already deployed DOCSIS 3.1 technology, which still has a long runway. And additional bandwidth tools available to us today include the conversion of the distribution network to DOCSIS 3.1 delivery for all products including video, broadband and telephony.
By allocating more plant Spectrum to DOCSIS 3.1 IP services, we have the ability to offer symmetrical gigabit plus speeds. We'll also continue to invest in DOCSIS 4.0 with key vendors in the rest of the industry for even greater capacity and functionality. The DOCSIS 4.0 specification allows for multiple path to reach 10 gig and higher speeds including full duplex of DOCSIS and extended Spectrum DOCSIS. Both 3.1 and 4.0 DOCSIS can be deployed in an economically efficient way as the market dictates.
Our network evolution strategy allows us to offer superior connectivity products to meet changing consumer demand and extend our growth strategy and drive free cash flow. Before turning the call over to Chris, I'd once again like to thank Charter's employees for their hard work, dedication and diligence throughout the pandemic. They've been asked to go above and beyond their regular duties and they have delivered.
Now, I'll turn the call over to Chris.
Christopher L. Winfrey -- Chief Financial Officer
Thanks, Tom. Turning to customer results on Slide 5 of our presentation, we grew total residential and SMB customer relationships by approximately 2 million over the last 12 months or by 6.8% and by 457,000 in the third quarter. Including residential and SMB, we grew our Internet customers by 537,000 in the quarter and by 2.3 million or 8.8% over the last 12 months.
Video grew by 67,000 in the quarter, better than last year's third quarter decline of 75,000 video customers. The positive performance was driven by churn benefits, particularly when bundled with broadband. And similarly, wireline voice declined by only 25,000 compared to a loss of 190,000 in the prior year quarter.
Mobile line net adds accelerated again to 363,000 in the quarter. To put what is already a strong third quarter subscriber results into perspective, remember that our Q2 results of 755,000 customer relationship net adds and 850,000 Internet net adds already included the benefit of our COVID programs. And our third quarter results reflect any churn out of those programs. Our year-to-date customer growth shown on Slide 6 remains the right metric for industry comparability given different reporting.
So, in the third quarter, we saw excellent retention rates for our remote education offer. Churn has been similar to regular new customer acquisition churn. We've relaunched the program very late in September with de minimis impact on our third quarter Internet net adds. Going forward, we expect the acquisition volume of this offer to be significantly lower than the original program and given the high retention rate of customers added during the first half of this year, we won't be breaking out this offer separately. Our Keep Americans Connected program completed in late June and we saw a good retention of those customers in the third quarter.
In the second quarter, we put approximately 200,000 customers that were past normal disconnection back into current status through a write-off of their debt. And so far, the vast majority are paying with minimal difference to normal customers. So the retention has been much better than our expectations. The development of customers' ability to pay generally though through employment or subsidies remains the key driver for our short-term residential outlook.
As I mentioned last quarter, our customer growth performance should be measured by our full year performance rather than a particular quarter. As the third quarter progressed, we could already see the market returning to more normal churn activity and net add levels and we expect that to be the case in Q4.
Turning to the financials, on Slide 7, as we expected, there continued to be moving parts due to COVID, and I'll reference some of those items, which we've again laid out on Slide 9 of today's presentation with full year summary on Slide 19. Residential revenue grew by 4% in the quarter, primarily driven by accelerating relationship growth in similar PSU, bundled and video mix trends we've seen over several quarters.
The 6.9% customer relationship growth in residential was partially offset by a $218 million one-time adjustment for estimated sports network rebates that we intend to credit to video customers. Due to accounting treatment, which I'll cover in a moment, not all of that rebate estimate was offset in the current period expense. SMB revenue grew by 1.5% and while revenue growth was slow this quarter due to the first half volume and SMB customers that remain on our seasonal plan, our customer growth has accelerated despite a still tough economic climate for small and medium business.
Spectrum enterprise revenue declined by 4.3% year-over-year driven by the sale of Navisite in the prior year period and the continued pressure from the wholesale side of the business. While the comparability issue for Navisite goes away after Q3, wholesale in particular, cell tower backhaul has been challenged and probably continues that way until late next year based on current activity.
Retail enterprise, which is the vast majority of our enterprise revenue is growing around 6% driven more by pre-COVID sales in the last six months performance. As Tom mentioned, enterprise sales activity has now pick back up despite limited on site access. As those new sales get installed in the subsequent months, we expect enterprise revenue growth can recover and begin to accelerate next year. Spectrum Reach, third quarter advertising revenue increased by 17% primarily driven by political. Excluding political, core ad revenue was down by about 10% which is reflected on Slide 9's COVID impacts.
So our core, very much tied to the economy is coming back and were significantly better than the second quarter with or without the recent heavy sports vote [Phonetic]. Obviously, we expect the fourth quarter to benefit from political as well. Mobile revenue totaled $368 million with $172 million of that being device revenue. In total, consolidated third quarter revenue was up 5.1% year-over-year.
Moving to operating expenses on Slide 8, in the third quarter, total operating expense grew by $36 million or 0.5% year-over-year. Cable operating expenses excluding mobile declined by 1.2% year-over-year, or 0.8% excluding Navisite with a number of COVID related items outlined on Slide 9. Programming decreased 2.3% year-over-year, reflecting the same rate, volume and mix considerations that we've seen in prior quarters and this quarter includes a $163 million benefit related to sports networks rebates.
The difference between the $218 million estimated credit to video customers, which lowered revenue and $163 million programming benefit relates to an expected reduction in sports rights content cost which is recognized in the produced content line over the remaining life of the contract similar to the delayed expense recognition in Q2 when games were canceled.
From a cash perspective however, we will provide our customers a bill credit for the rebates received from the sports program networks when those details are finalized. Regulatory connectivity and produced content expenses were essentially flat year-over-year and were comprised of lower regulatory and franchise fees offset by higher video CPE sold to customers and higher sports rights cost.
Cost of service customers increased by 0.4% year-over-year with meaningful productivity improvement, lower bad debt and higher wages and benefits as drivers. Bad debt expense was down year-over-year given surprisingly probably our best ever payment in collection trends. Excluding bad debt from both years, cost of service customers was up 7.5% year-over-year in the third quarter, primarily driven by 6.8% customer relationship growth, the hourly wage increase we instituted earlier in the year, COVID flex time and the timing of medical benefits cost.
In Slide 9 of today's presentation, we've isolated the temporary bad debt benefit as customers paid better than usual and the labor cost increased from an acceleration in frontline wage increases and benefits timing. I expect continued nonrecurring puts and takes on this line item for a few more quarters. Over time, cost of service customers should again grow at a slower rate than customer relationship growth due to lower transaction volume and higher self service trends despite the step up in minimum wages.
Cable marketing and sales expenses declined by 0.7% year-over-year as our unit growth did benefit significantly from lower churn. Other expense declined by 2.5% year-over-year primarily due to Navisite cost in the prior year period. And mobile expenses totaled $456 million and they were comprised of mobile device costs tied to device revenue, customer acquisition and MVNO usage cost and operating expense.
Mobile EBITDA is still negative because of customer growth cost [Indecipherable] by much less despite the higher growth. Another way of describing that trend is that we have now crossed 2 million lines and our mobile service revenue now exceeds all regular operating cost excluding acquisition and growth related mobile cost.
In total, we grew adjusted EBITDA by 13.6% in the quarter when including our mobile EBITDA loss of $88 million. Cable adjusted EBITDA grew by 11.7%. We generated $814 million in net income attributable to Charter shareholders in the third quarter and capital expenditures totaled $2 billion in the third quarter. Our third quarter capital expenditure shows we've continued to invest to support current and future growth.
We invested significantly in continued capacity upgrades at the national and local levels to stay ahead of higher data usage. We have not slowed down on new build, including construction in rural areas. We continue to purchase significant DOCSIS 3.1 modems for new connects and swaps as well as a high attach rate for advanced in home Wi-Fi service. We also continued to invest in facility improvements, back office systems and mobile store build-outs.
For the full year 2020, we still expect cable capital expenditures as a percentage of revenue to decline year-over-year, but maybe only slightly due to the significant customer growth and related CPE and capacity investments. We generated $1.8 billion of consolidated free cash flow in the third quarter and excluding our investment in mobile, we generated $2 billion of cable free cash flow, up about $500 million versus last year's third quarter. Currently, we don't expect to be a meaningful federal taxpayer until 2022.
We finished the quarter with $1.3 billion of cash and $4.7 billion of availability under our revolver. As of the end of the third quarter, our net debt to last 12 month adjusted EBITDA was 4.3 times, or 4.2 times if you look at cable-only. Earlier this month, we issued $1.5 billion of 12-year high yield notes at a yield of roughly 4%. Pro forma for our recent financing activities, our current run rate, annualized cash interest is $3.8 billion, and we remain comfortable in the middle to high end of our target leverage range of 4 times to 4.5 times.
During the quarter, we repurchased 6.1 million Charter shares and Charter Holdings common units totaling about $3.6 billion at an average price of $592 per share. We will always evaluate the best use of our capital to generate long-term returns for shareholders, be it organic investments such as our launch of mobile or network edge-outs, accretive M&A or purchasing of our own shares and probably in that order.
The prioritization of organic investments is because there is a high demand for our products across every part of our footprint, which is why we continue to aggressively build out more broadband passings and ensure that our network is well invested, ready, and working for future opportunities. As the environment continues to evolve, our goal is to stay focused on what we do well and to execute a proven operating strategy that works for customers and employees to create shareholder value.
Operator, we're now ready for questions.
Questions and Answers:
Operator
[Operator Instructions]. And our first question comes from the line of John Hodulik from UBS. Go ahead please. Your line is open.
John Hodulik -- UBS -- Analyst
Okay, thanks guys. Couple of questions about broadband. I can't help but notice that you guys talked about the fact that you're competing well really regardless of the infrastructure that you're going against. Obviously strong numbers across the board for the industry in terms of broadband net adds. Can you talk about how you're competing against fiber competitors and sort of market flow shares, if you could some -- cite some numbers there? And then the other number that stuck out to me was the 600 gigabytes of usage and the continued growth there.
It looks like maybe we're a couple of years away from a terabyte on average for broadband only customers. Tom, how does that affect the competition as you look out over the next few years? I think specifically against fixed wireless access, does it -- does it make it more difficult for fixed wireless to be a true competitor to sort of wired cable service?
Thanks.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Well, John, how do we compete with -- we have, it's not just the products, but the products do matter, and it's obviously what you're selling as a product, how much capacity, how much speed, how much throughput, what the reliability is. But also, how well you service it and how efficient you are delivering the product.
And so, we are competitive with the infrastructure that we have against all the various competitive infrastructures we go against, fiber, fixed wireless, satellite and copper-based high capacity networks. And so, our network is highly capable, it's easy to augment from a capital investment point of view, it's very efficient to augment, and we keep our product sets and our service sets better than our competitors and we prevail in most -- almost everywhere we operate.
How do I think about that going forward with the fixed wireless? I think that all of the various opportunities for competition require a significant capital investment by our competitors. And I think our network sets up better from a capital investment perspective going forward so that we can provide more capacity and more capability at lower costs than our competitors.
So it's a very competitive environment. There's a lot of different ways of making the competition work, but I think our network has superior capabilities properly managed.
Christopher L. Winfrey -- Chief Financial Officer
John, I would just add, I kind of went out of my way in my prepared remarks to say if you want to compare against some of that competition, you really need to take a look, because of the moving parts throughout the different quarters. You need to look at year-to-date results and compare that in terms of what's Charter doing in front of competition, as Tom mentioned, we have competition essentially everywhere we operate. We've had that, it's not new. But we're performing very well, and if you take a look at our Q3 year-to-date results, I think that's probably the most indicative way to really look at it and think about the performance.
John Hodulik -- UBS -- Analyst
Okay. Thanks guys.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Thanks John. James, we will take our next question, please.
Operator
Our next question comes from the line of Ben Swinburne from Morgan Stanley. Go ahead please. Your line is open.
Benjamin Swinburne -- Morgan Stanley -- Analyst
Thanks, good morning. Picking up a little bit on the same themes that John asked about. I want to ask Tom about the network evolution you discussed going to IP video. Just so I understand, are you taking down MPEG across the system? And is that something that requires a swapping out of boxes? Just what are the -- what are the capital business implications of moving video over to IP on 3.1? Obviously that seems like a big transition from the historical approach.
And then again, just going back to the broadband results this year across the industry, it seems like we've pulled forward penetration in broadband in United States, if you just look at the year-to-date growth. It's an unbelievably strong year across the industry.
So I'm just wondering, I don't know Chris, if you want to take this one, but just thinking about lapping this year, next year and thinking about the quality of the customers you brought on, I know you've seen good churn stats so far. But should we be thinking about this pull forward having maybe lapping this next year and next year is going to be a below average year? I don't know if you have any thoughts on sort of where we go from here as we come out of COVID, which has obviously just pulled all this -- all this growth into 2020. Thank you both.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Well, OK, Ben. So how does the network work? Right now, we actually run three, actually more than three, but
I'll -- three major networks inside of one physical infrastructure. So we have DOCSIS 3.1 which is a -- which we use capacity to deliver IP-based services to specific modems, households and customers. We also have a DOCSIS 3.0 infrastructure inside of our network and we have a QAM based video infrastructure.
Most of the network is still dedicated by QAM based video, the traditional cable TV service and delivered to consumers that way. So you can actually -- and today, we have multiple ways of delivering video to our customers and other services. And we have 10 million app based streaming products, devices connected to our network where the customer has downloaded an app and we're feeding that app our app with a full bundle of video packages and the consumer brings their own device.
We also have a significant distribution of QAM based traditional cable TV services, and we are planning on mixing the two together in the same device and we do for instance, we have Netflix on our set-top boxes in a device, we provide, but it's actually being delivered through a different path to the box. So the box will look at video from the traditional cable TV path and will also look at the -- at the new IP path and combine them together in a seamless experience for the customer.
So we have the ability to manage CPE and customers through time and manage the way we use our network in an efficient way to provide a full range of services. And with regard to MPEG, you know, even if we deliver IP video, we'll -- as we do, we still use MPEG to do it. That's the digital format, the video is in. And there is an opportunity through compression going from MPEG-2 which is still widely distributed by us to MPEG-4 and there is opportunity through the addition of products to what we call switch to video, which can be either IP or MPEG traditional QAM based MPEG, and we can manage, how much is switched, how much is in MPEG-2, how much is in QAM, how much is in DOCSIS 3.0 and how much is in DOCSIS 3.1 and actually run all of that at the same time.
So we have a lot of room and I think the key takeaway is that traditional video is still the largest single -- it's more than half the capacity of the infrastructure.
Benjamin Swinburne -- Morgan Stanley -- Analyst
Yeah. But you don't need to replace boxes in order to move that...
Thomas M. Rutledge -- Chairman and Chief Executive Officer
No
Benjamin Swinburne -- Morgan Stanley -- Analyst
To make that network... [Speech Overlap]. Okay, that was the key point, yeah, got it.
Christopher L. Winfrey -- Chief Financial Officer
Ben on your broadband question, I'll take a crack at it and Tom may want to add as more to it. The industry is growing at a faster pace, and we've taken in a higher amount of share across all areas of our footprint and infrastructures as Tom mentioned. Where you're seeing that come from is broadband networks and also the acceleration of mobile only in addition to the significant share shift that we're seeing as cable generally.
I don't think whether that was a pull forward or not, I don't know, but it doesn't go backwards. I think the demonstration, the need for the product is there. I don't think it goes away. I think it's a permanent either shift or trend of reducing the mobile only and requiring more broadband in the household.
And what I think we are seeing already and I mentioned it in the prepared remarks is late in Q3 you could already start to see the market moved to more normal transaction activity, and that includes both churn and sales.
We think that's indicative of where Q4 is probably heading and I think probably for next year as well you will have higher levels of mover churn and market churn and as a result, you have higher sales, as that moves through. And I think next year right now, it probably looks more like a normal year as opposed to 2020.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
The other thing I would add just in terms of longer run trends, yes, COVID had some impact on broadband adoption, but so does the change in the video business that's going on rapidly. And as more and more people are using IP connected devices to bring video services that traditionally would have been delivered either over the air or by cable. That increases overall demand for broadband in the home. And I think that also is simultaneously going on.
So you have a -- a sort of overall demand change as a result of what's really going on in video. And so I don't know that it changes adoption rates so much going forward, but as it just shifted the entire amount of people that would be interested in having a in-home broadband service.
Christopher L. Winfrey -- Chief Financial Officer
Which kind of ties into John's question about the suitability of wireless access over time when you have that kind of throughput going through, I agree.
Benjamin Swinburne -- Morgan Stanley -- Analyst
Those are good points, thank you.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Thanks, Ben. James, we'll take our next question, please.
Operator
Our next question comes from the line of Jessica Reif Ehrlich from Bank of America. Please go ahead, your line is open.
Jessica Reif Ehrlich -- Bank of America Merrill Lynch -- Analyst
Thank you. So even with the increase in broadband demand which is quite evident, you posted video net ads for the second quarter in a row significantly bucking industry trends. So first, have trends in fourth quarter indicated that you can continue those trends or was it COVID-related, is the [Indecipherable] that you were talking about. And second, what specifically about your offering, do you believe consumers are responding to. And then just as a second topic, Tom, just a follow-up on your advertising comments you said that the core underlying advertising is 90% back to normal, what do you think of the drivers there, because it still seems that local businesses are struggling and so what are you doing differently or what metrics do -- you know, what data you do using that's different?
Thomas M. Rutledge -- Chairman and Chief Executive Officer
All right, well, you know, if you look at our overall connectivity growth as Charter versus the industry, we have higher and faster connectivity growth generally speaking to the industry and as a result of that, we're pulling through video with that growth.
If you just think about overall video penetration as a percentage of household and you think about changing households over to your network, you're going to -- you're going to pull through a certain percentage of video and if you grow fast enough, you'll growth video as a result of that. And we said that in the last call in terms of why we think our video growth is positive.
We don't think that the overall video marketplace has changed, meaning we still think fat bundle is a very expensive video are under pressure and will continue to be. And so you're going to have continued erosion of that bundle we think through time. But we're just growing faster than that erosion.
With regard to ad sales, I'll let Chris answer that, but I want to say one thing about local businesses, they are under duress. But you know, our SMB growth rate is higher this year than it was last year in the third quarter and so we're actually seeing a lot of -- yes, there is a lot of damage out there, but there's also a lot of reinvention and a lot of new business formation and -- at the very small business level and we're taking advantage of that.
Christopher L. Winfrey -- Chief Financial Officer
Jessica, the Spectrum Reach, which is our advertising group as you mentioned is back to 90% of prior year on the non-political, sort of local advertising. And from what I've seen so far, most of our peers are reporting at kind of a similar range of their core advertising being back.
And so I don't -- I don't think we're that unique. I think for the industry, some of that benefit was the lack of advertising in Q2. If people wanted to get back into the market, some of that was tied to -- a lot of that was tied to what Tom said is where the SMB space is behaving well for us on the business side.
And, but also the sports timing in the third quarter. You had a doubling or in some cases tripling of sports activity inside of the third quarter related to a lot of the delayed seasons for the different sports. And that was encapsulated inside of Q3. So that admittedly helped.
And from a Charter specific perspective, we have New York City and LA, and they've been more locked down than other markets. So from an economic perspective, we have those slight drag or delay in that returning relative to others. But if you really step back, the -- despite the overall market having negative video trends and everything that's said about the traditional advertising space, we have a good runway for growth in front of us, because of our ability to monetize the long tail of the inventory by tools that we've developed to really drive impression based viewing measurement, and to be able to sell our product or advertising product on that basis.
So traditional channels that weren't able to be monetized are now able to be monetized and packaged in a really different way and sold at a different price. And together with addressability and a lot of the additional interactive advertising features that you're well aware of that we've been adding to the portfolio. So even in an environment where video is slightly declining, I think absent a pandemic, we have the ability to grow our core advertising in political and non-political years alike.
And so, that business is outside of the pandemic, that business is actually in very good shape.
Jessica Reif Ehrlich -- Bank of America Merrill Lynch -- Analyst
Great, thank you.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
James, we'll take our next question, please.
Operator
Our next question comes from the line of Jonathan Chaplin with New Street. Go ahead please. Your line is open.
Jonathan Chaplin -- New Street Research -- Analyst
Thanks guys. Two quick ones. So Chris, you mentioned that next year will be a more normal broadband year. But we -- you've been accelerating broadband subs ever since the Time Warner Cable acquisition. What do you think of is a normal broadband subscriber growth here? Is that sort of 6% year-over-year growth? And then on...[Speech Overlap]
Christopher L. Winfrey -- Chief Financial Officer
We love you Jonathan. [Speech Overlap] your next question.
Jonathan Chaplin -- New Street Research -- Analyst
I still expect an answer to the question though, Chris.
Christopher L. Winfrey -- Chief Financial Officer
Yeah.
Jonathan Chaplin -- New Street Research -- Analyst
And then on EBITDA growth, the contribution from wireless this quarter was also, I mean, I assume that just continues, the losses continue to recede and that'll be a propellant for EBITDA next year as well. Do you have a sense of what that could contribute to year-over-year growth for EBITDA next year?
Christopher L. Winfrey -- Chief Financial Officer
So on both of those kind of bit of guidance questions which isn't what we do. The honest answer to your first question is we don't know. And if we see trends reverting back to normal, which mean more normalized growth, does that mean more like 2019, does that mean continued acceleration somewhere? Yes, I guess, is the answer to both of those questions, we don't know.
But I think it's going to be good either way, and so we're really positive on the outlook for broadband. Obviously as we look further out, to the extent that we're doing a rural build and expanding our footprint to the extent that mobile really has a significant impact both acquisition as well as churn, to the extent that there is additional mobile substitution that declines for all the reasons that we talked about before, all of those things will be positive relative to our normal growth rate.
And so, we need to see how all that develops. The wireless side to your point, you can look at it in a few different ways. You can take a look at our losses per mobile line, which is doing very well. You can think about it in terms of what I said before is that once we got to 2 million lines which we crossed over inside this quarter that it's now an incrementally positive business, but for the subscriber acquisition cost.
So it's already EBITDA positive if we decided to stop growing, which of course we won't do. And so, the answer to your question is, yes, it's going to continue to get better, but the amount that it continues to get better in terms of its contribution to our EBITDA performance really depends on the growth rate of wireless and subscriber acquisition cost. The faster you grow, the more you're going to spend and we're going to try to grow as fast as we can.
And so, it depends on the growth.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
You know, the other way to think about mobile is yes, it's EBITDA positive going forward and it's -- and as it's currently priced, but if you grow mobile rapidly, as we are, it -- you know, you'll grow your broadband rapidly too.
Christopher L. Winfrey -- Chief Financial Officer

Our next question comes from the line of Kannan Venkateshwar from Barclays. Go ahead please. Your line is open.
Kannan Venkateshwar -- Barclays -- Analyst
Thank you. Chris, I guess a couple for you. The first is on the gross addition front, I mean obviously because gross adds have been really strong this year, and many of them have come in at a lower price and in general gross additions come in at a lower price, so when you look at ARPU next year, it should be stronger than normal because of the cohort [Phonetic] shift this year and the bigger volume of gross addition.
So I just wanted to understand if that's the right way to think about it or if there are other things that offset that benefit? And then secondly, in terms of home passings, you guys have been I think growing at more than 2% this year, which is higher than household formation and higher than most others in the industry. If you could give us some sense of the attach rates for these newer homes passed versus your existing base to give us a sense of what the -- the mix of these newer homes looks like, that would be useful.
Thanks.
Christopher L. Winfrey -- Chief Financial Officer
And so, I think the answer to your first question on gross additions is it's going to be a little bit of a mixed bag. Q2 of this year definitely had higher gross additions for all the reasons that we talked about inside of Q2. Q3 did not. And as I mentioned, the activity levels dropped significantly both on those particularly related to churn, which also has the impact of reducing sales across the entire market because you have less flow.
And so inside the third quarter, one of the reasons our marketing and sales costs were so low despite the significant growth that we had was tied to that very fact. And so, I think you're going to see a mixed bag inside of next year as it relates to ARPU impacts from promotional pricing roll-off.
On top of that I would argue that the biggest driver of our ARPU development really is less about the individual PSU pricing at roll off and it ties much more to the amount of single play sell-in. And so, that's the biggest driver that's going on together with the video tier mix. So when you think about our success in selling Spectrum stream and choice and essentials products has a bigger impact than the mix that you were referring to.
On the homes passed, when we do new construction and depends as -- what we call brownfield or greenfield but we have pretty steady penetration curves over each vintage if you want to call it that, of what we're building. And that's what gives us a lot of confidence to get to do more of it, because we can see a high level of consistency in terms of our ability to get to very high terminal penetrations when we build into markets.
And so, that's what gives us confidence in our ability to go, extend that investment concept. I don't know if that's helpful in answering the question, but we'd like the penetration, the speed and the curve of the penetration that we're getting in these new passings.
Kannan Venkateshwar -- Barclays -- Analyst
Got it. Thank you.
Christopher L. Winfrey -- Chief Financial Officer

Our next question comes from the line of Craig Moffett with MoffettNathanson. Go ahead, please. Your line is open.
Craig Moffett -- MoffettNathanson -- Analyst
Hi. Thank you. Two questions if I could. First if I can just stay with the -- what you were just talking about with the adoption curves in new market. Can you -- can you share with us how much of this quarter's growth came from newly passed homes or is there homes passed within the last 24 months or so, just to get a sense of where we're seeing penetration of newly opened markets versus where we're seeing increases in penetration of mature markets. And then -- and then separately, just given how promotional the wireless market has become in the last few months or the last month or so in the wake of the iPhone launch, how does that affect your thinking about your own promotional stance in customer acquisition for -- for wireless and how should we think about what cost that might bear for the fourth quarter.
Christopher L. Winfrey -- Chief Financial Officer
So Craig, why don't I take the first one and Tom can grab the second. I don't have the number in front of me, but it's -- it's not the material driver for our net additions. The new passings construction, it's been relatively small when you consider that compared to our 52 million passings overall.
It's helpful, but it's not the material driver of our growth. A simple way to think about it is if you think about Greenfield new construction anywhere historically past couple of years than 500,000 to 600,000 homes, and so that gives you what you would need to go model and say [Phonetic] apply an adoption curve to that number of passings and you can get to a number and what you'd see is, it's meaningful, but it's not material to our overall Internet net additions growth rate.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Yeah, I'd say it's meaningful, but not material. I agree with that. Promotional, you know, our basic proposition when you think about wireless is that we can save consumers a lot of money. And if you look at the average wireless bill that most households are paying, they can connect to us and buy the right package from us and save a significant amount of household spent telecom spend, and reallocate that to us, that's our primary objective.
And we don't -- we have the ability to switch customers over, who already have a wireless account to our product and we're not driven by new hardware for the consumer to drive our business. The consumer can bring their hardware with them and connect to us and save money. And so, yes, we are oriented toward making our price successful in the marketplace, and we'll have to complete with that price, but we already have a significant price discount to what most people are paying for their wireless service and as a result of that and we've had accelerating growth in wireless connections.
And so, we're offering real value to consumers and real overall savings by having them connect to us, both for their broadband and their wireless products.
Craig Moffett -- MoffettNathanson -- Analyst
Thanks. And Tom, I just want to say, I was delighted to see the extension of your contract this morning. So, are we to understand that is you are now under contract until the end of 2024?

Our next question comes from the line of Phil Cusick with JP Morgan. Go ahead please. Your line is open.
Philip Cusick -- JP Morgan -- Analyst
Hey, guys. Two, if I can. First a follow-up on Jessica's question. What is the video attach rate to broadband sales these days and how has that changed in the last few years? And second, a little more on wireless, Tom, you talked about a network build over time with the inside out strategy. How does that take advantage of spectrum and does cellular get integrated into your home routers over time, do you build that in dense outdoor markets like Comcast talked about yesterday, what's the sort of the plan over time?
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Yeah. Yes, I mean the attach rate of video to broadband is -- has been declining steadily and that's because the overall penetration of video, traditional video is declining steadily. And so, and so the reason we are growing video isn't because that ratio has changed. It's because we're growing broadband faster. And therefore, pulling some video through with it.
Christopher L. Winfrey -- Chief Financial Officer
Phil, the interesting stat attached to that is related, is we really don't sell video. We sell package connectivity services. If you asked how many video single play do you sell, it's about 5% of our video sales are coming through in single play. So we really don't sell video. We sell what is an application or service attached to the connectivity service.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Yeah. And with regard to your second question...
Philip Cusick -- JP Morgan -- Analyst
Maybe I wasn't clear... [Speech Overlap] I was just going to say what, so what is if 95% of your sales are attached to broadband and not, and so what is video as a percent of revenues?
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Yeah. We're not providing that, I think for competitive purposes. But we're saying, it has been declining and that hasn't changed. We've just sold more broadband, which is why we have more video.
Philip Cusick -- JP Morgan -- Analyst
Okay, thanks.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
And so this inside out strategy and how do you use Spectrum, and can you put it in the house, you know, we interestingly, our WiFi capabilities and available spectrum for WiFi has continued to improve. The FCC has just granted significant amounts of WiFi Spectrum to the public for use and we plan to use that spectrum inside dwellings.
And so, when I, when we think about spectrum and the spectrum we recently got with CBRS, it's -- can you augment your WiFi Spectrum with the CBRS spectrum to move traffic on to your own network that you might be paying someone else to carry? And the answer is yes, and you can do that in an efficient way, depending on the location and where you put the radio in such a way that you can actually reduce your overall cost and as a result of that cost reduction, you get a return on investment on the capital you spend on both the Spectrum and the radios that you've deployed.
There were applications where CBRS spectrum or WiFi Spectrum used differently than it has in the past, but can be used in enterprise connectivity using 5G factory kind of notions where you would control the inside of a building using spectrum.
So there are individual products where you would want to have multiple radios potentially in the same environment whether you need to do that in a household in the short run or not is not that clear because there's so much WiFi Spectrum available.
But there are applications that I can think of like farms and other places like that where CBRS could cover the whole property, 100 acres or 500 acres of property or even more for connectivity services. So it's a tool, so I look -- we look at spectrum as a tool to extend the connectivity and we plan to use it in ways where it takes our cost structure down.
Philip Cusick -- JP Morgan -- Analyst
That's helpful. Thanks, Tom.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Thanks, Phil. Operator, we'll take our next question, please.

Our next question comes from the line of Bryan Kraft with Deutsche Bank. Go ahead please. Your line is open.
Bryan Kraft -- Deutsche Bank -- Analyst
Hi, good morning. Wanted to follow up I guess on a couple of topics. So, one for Tom, and then one for Chris. Tom, I wanted to follow up on your earlier comments on the HFC network. I think there's been more talk recently in the industry about operators over building the fiber to the home, the advantages obviously being upstream and latency.
How are you thinking about the trade offs now between deploying more fiber to the home versus continuing with HFC particularly given some of the changes in upstream traffic patterns during COVID. And can you just help us to understand how that upstream bandwidth at latency improve as the DOCSIS infrastructure evolves?
And then, Chris, I wanted to follow up on the build-out or the inside out strategy that Tom mentioned in his prepared remarks. Can you give us any color on the magnitude or the significance of the capital investment that we could expect there and maybe just some timing comments, broadly speaking, and is that -- is that a long time to reach positive ROI or is it a fairly short duration? Thank you.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
So, Bryan on the HFC plant, we think that there is a lot of capacity in the HFC plant both downstream and upstream, and we think that given the current marketplace and utilization behaviors of consumers that we have plenty of upstream capacity and we have a pathway using DOCSIS 3.1 technology and later 4.1 technology to continue to increase that.
And we have a vision that in the event that there is a transformative product set that needs upstream, that would create value for consumers and then for us that we could fairly rapidly upgrade our plant to get a massive change in upstream capability.
So we -- we build with fiber on the increment, because it's cheaper, but we think that the HFC plant can be equal to fiber from a capability latency capacity perspective for years to come. And we think that with relatively small capital investments compared to replacement cost new which is what fiber is that, that we can upgrade the network and be competitive for a very long period of time.
Christopher L. Winfrey -- Chief Financial Officer
And as it relates to the CBRS build out, it's really a function of a few variables, one is the number of subscribers that you have, the more you have, the more economical -- with the usage of those subscribers, the amount of WiFi offload that you can get already. What is your rate on MVNO and what's your density and the build cost.
And as Tom mentioned, we wouldn't be building just to build the network. We'd be building tied to a guaranteed effectively cost reduction and so the ROI is not only relatively quick, but it's very clear and there is very low risk and so we're not -- we're not building any inside out strategy just to have a network or for other network type -- for reasons other than the cost reduction.
And I don't think that it's going to be material in the short term, I think it all occur for many multi-year period. And you could argue that as the mobile retail store build out declines for mobile that could be substituted over time with some additional build out, which has a direct correlation to cost reduction. And as we start to do that, we're not doing that yet, we'll probably provide a little more color on what we think the effective pay back of that is.
But I think the thing you should take comfort is that we're not -- we're not building just to build, and it's going to be tied to your cost reduction and ROI.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Yeah. The thing I would add to it is, yes, we have the $460 million of cost for CBRS spectrum, but the incremental capital is very specific to the location and the amount of traffic that we would save and essentially radio by radio kind of investment. It doesn't require building out a complete footprint. It's actually opportunistic by location.
Bryan Kraft -- Deutsche Bank -- Analyst
Great. Okay, thanks.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
Thanks Bryan. James, we have time for one more question.
Operator
Thank you. And our final question comes from the line of Michael Rollins with Citi. Go ahead please. Your line is open.
Michael Rollins -- Citigroup -- Analyst
Thanks and good morning. So over time, you've given us a lot of insight into broadband consumption trends. I was curious if you can give us an update of how your video customers are now engaging with your platform, especially as you're growing subs year-to-date with respect to maybe what percentage of your customers engage with your VOD platform or the digital applications that you offer or the cable networks offer and need to be authenticated through Charter and then you can take all of that in aggregate, how much time they're spending with you guys, and then as you roll that up then, how does that instruct your video strategy going forward in terms of the way you want to aggregate and distribute content. Thanks.
Thomas M. Rutledge -- Chairman and Chief Executive Officer
I don't know that I can answer that directly except to say this, we track what our customers do with their video products and we also track how they rate our applications and what their customer experience is, and what our availability of content is to sell to the consumer. And we try to mix and match that in a way that we create an overall value in the relationship we have with the customer, but also create a product that makes money. And we've had some success in managing new ways of delivering video.
As I said, we have over a 10 million users who are getting their service through applications as opposed through traditional hardware. And so we look at the business as evolving. We think that people will continue to buy rich packages for years to come, but we also think there are other opportunities to sell a variety of video services to consumers in different formats and that we can improve the customer experience by being a good place for consumers to interact with us to get those video services.
And so we're working toward that and we are making some success. And we're actually optimistic in the very long-term about our video business.
Michael Rollins -- Citigroup -- Analyst
