Steam is an online store for PC games. It sells digital versions of popular games, and it's business model is roughly equivalent to Apple's iTunes.

During GameStop's (GME 0.10%) earnings call on Tuesday, management bragged about the amount of Steam gift cards the company had sold in the previous quarter. This would be like a Borders executive, back in 2009, boasting about the amount of Amazon giftcards his company sells.

GameStop will benefit from the upcoming console refresh -- demand for the next generation of consoles from Microsoft (MSFT -1.84%) and Sony (SONY 0.37%) should bring more consumers through GameStop's doors.

But long term, GameStop remains heavily exposed to a shift taking place in the sector. Games are going digital, and this trend is only being exacerbated by the new consoles.

GameStop looks great in the near-term

In the immediate future, GameStop's business looks great. Both Sony and Microsoft will release their next video game consoles this holiday season, and both could sell exceptionally well.

Microsoft's last console, the Xbox 360, was released in 2005, while Sony's PlayStation 3 came out in 2006. This 7-8 year console refresh cycle is unprecedented in the industry -- prior to that, new consoles had generally been released every five or six years.

GameStop has said it's seeing a tremendous amount of excitement surrounding the new consoles -- and that makes sense, there's likely some pent-up demand among gamers.

The problem is that this next batch of consoles will be unlike their predecessors. Their level of reliance on the Internet -- and hence the digital distribution of games -- will be far greater than past consoles.

The Xbox One could be the last Xbox you ever need to buy

Initially, Microsoft was planning to make the Xbox One the most digital console ever. If it had stuck to its plans, owners of the Xbox One would've had to keep their consoles connected to the Internet at all times.

Xbox One games would still exist in physical form, but the disc itself would be largely unnecessary. Games were to be installed onto the system, like PC software, and then tossed aside -- making it difficult, if not impossible, to resell games.

After widespread consumer backlash, Microsoft has backed away from these plans. The Xbox One will, like the other Xboxes before it, play disc-based games from the actual disc, and will not require a constant Internet connection.

All good for GameStop, right? Well, not really. For starters, Microsoft clearly sees the advantages in pushing digital games. It might not be able to do it right now, but it seems reasonable to expect the company to try again in the future.

But more importantly, the Xbox One could be the last console gamers ever buy. As the Official Xbox Magazine notes:

Sure, the basic hardware will date, but cloud computing offers near-limitless potential-and as broadband connections are only going to get better, by the time the Xbox One starts to look like it's running low on horsepower or storage space, you'll be able to hand the job off to the Xbox Live servers rather than having to upgrade.

With the Xbox One, Microsoft is pushing the power of cloud computing. Microsoft has invested in thousands of servers its making available to game developers. At first, utilization of these servers should be limited, but eventually, games could come to exist wholly in the cloud.

When that happens, there will be no reason to buy a physical version of the game -- it will exist purely in digital form.

Sony wants to create a Netflix of games

Sony's plans for gaming are even worse for GameStop. Rather than build a server farm for partial cloud support, Sony is diving head-first into streaming games.

Last year, the company bought streaming game start-up Gaikai for $380 million. Gaikai's technology allows for games to be streamed directly from Sony's servers to a player's console, and it will make an appearance in the PlayStation 4.

It won't work at launch, but Sony says that, eventually, players will be able to stream PlayStation 3 games to their PlayStation 4.

In an interview with The Guardian, Sony's president of worldwide studios said the company dreams of offering a subscription-based, streaming games service -- a Netflix of games. If PlayStation players are getting their games streamed to them, they aren't going to need to buy physical copies.

But that's a ways off. Sony has plans that could hurt GameStop much more in the immediate future.

Sony is planning a trade-in program of its own. Gamers who purchase multi-platform games for their old console (Madden 14, for example, will be released on both the PlayStation 3 and 4) will be able to trade that game to Sony for a PlayStation 4 version -- specifically, a digital version.

Borders, Tower Records, and Blockbuster

And this is just the existing players, not to mention reports that Apple, Google and Amazon are planning (digital) consoles of their own.

What GameStop is going through is nothing new. It's a trend that's played out countless times in the past. Companies like Borders (books), Tower Records (CDs), and BlockBuster (DVDs) ran into the same problems when their businesses went digital.

Although GameStop shares may continue to appreciate in the next few quarters, longer-term this company is existentially challenged.
