Sling TV made its debut in January 2015, and it's quickly grown to around 1 million subscribers. The over-the-top streaming television service from DISH Network (NASDAQ:DISH) offers several different skinny bundles priced from $20 to $40 per month. DISH decided to lump its Sling TV customers in with its regular satellite TV subscribers despite the huge disparity in average billing per customer. Even so, DISH lost 420,000 net subscribers through the first three quarters of 2016.
Without the Sling TV subscribers, that number would obviously look much worse. DISH's satellite business has run into a wall, as traditional cable companies such as Comcast (NASDAQ:CMCSA) take back share of the pay-TV market. Services such as Sling TV are eating away at the market for traditional TV service, such as DISH Network's satellite business.
The innovator's dilemma
In an interview in March 2015, shortly after Sling TV's launch, DISH CEO Charlie Ergen said there's "no question [Sling TV] will cannibalize our business." Originally, Ergen believed Sling would be incremental to DISH's existing business, but he quickly changed his tune. While it's unclear exactly where Sling TV subscribers are coming from, DISH Network would certainly be worse off without the service.
DISH has the first-mover advantage with Sling TV. Sony (NYSE:SNE) released a similar service shortly after Sling, but it contains a lot more channels, and it's priced similarly to traditional cable bundles. Comcast started offering its own streaming package containing broadcast networks and HBO, but it's only available to Comcast Internet subscribers.
Sling TV has a lot of competition coming down the pipeline. AT&T (NYSE:T) plans to launch its own streaming package in November called DirecTV Now. Hulu and YouTube are reportedly working on similar live TV streaming services as well. Amazon.com (NASDAQ:AMZN) is reportedly working on a skinny bundle of channels for a streaming service, and it already has deals in place to add premium network subscriptions to Amazon Prime's streaming service.
The thing about Sony, Hulu, YouTube, and Amazon is that none of them has an existing television business. The advent of Internet streaming reduces the cost of entry for competition in pay-TV. As such, it's important for traditional companies such as DISH Network and Comcast to launch pre-emptive strikes with services such as Sling TV and Stream.
The impact on business
Despite Sling TV's $20-per-month price point, DISH Network has been able to increase its average revenue per subscriber. Last quarter, it increased ARPU 3.6% year over year to $88.44 per month. This, however, was more a function of a price increase and fewer promotions aimed at DISH's 12.5 million or so satellite subscribers than anything else. Weighed against the million Sling subscribers, the impact was minimal.
But as Sling TV grows and eats more into DISH's satellite business, investors will probably see a decline in average revenue per subscriber. Ergen believes some of the lower billing revenue will be offset by improved ad revenue, considering digital ads can be tailored to each individual viewer.
The real offsetting factor will come in operation expenses. Customer acquisition costs for Sling TV are significantly lower than for satellite. DISH doesn't need to send over a truck, install a satellite, and provide and set up set-top boxes for customers of Sling TV. It just offers a one-month free trial. DISH's subscriber acquisition cost per customer declined 13% last quarter. Its low cost of acquisition allows DISH to sell Sling for a competitive price.
On the other hand, scaling the service is a challenge. With live TV there's no room for buffering, and outages are less tolerated than video on demand. DISH faced challenges early on, as Sling TV customers tried to tune in to the NCAA Basketball Championship Tournament and were met with blank screens. Scaling to prevent such outages from recurring is a major expense.
Overall, replacing a $100-per-month customer with a $20-per-month customer isn't as terrible as it looks. It's certainly better than completely losing subscribers to competition, whether that's an old cable company or a new tech start-up.
