In a recent interview with BuzzFeed News, Apple CEO Tim Cook said universal search in Apple TV is not something that the company plans to reserve for key content partners. “At launch we’ll have iTunes, Netflix, Hulu, Showtime, and HBO — so we’ll have five major inputs into universal search initially,” Cook said. “But we’re also opening an API, so that others can join in.”
Every single developer building apps for the Apple TV is going to want to make use of that API.
