Steam's Big Picture Mode will enter beta tomorrow, according to a report in the New York Times.
The feature on Valve looks at the company's odd corporate structure, their wearable computing and VR efforts, and how Valve are competing with app stores built into operating systems, like the Mac App Store and the Windows 8 store.
The NYTimes say: "on Monday, the company will begin a public test of a new television-friendly interface, Big Picture, for buying Steam games and playing them on computers in the living room."
We've previously reported Valve are agnostic as to the direction Big Picture Mode will take. Valve's business director, Jason Holtman explained that "we'll ship it and see what happens."
Which is exciting.
