The universal search functionality on the latest Apple TV recently saw NBC added to the list of content providers included in results in the United States. The addition is part of an ongoing expansion that most recently saw CBS added last month.
Universal search on the Apple TV allows users to search for content using Siri or text entry and see a list of providers offering a given movie or TV show. For providers that offer only certain seasons of a show, those limitations are reflected on the results screen.
With the addition of NBC, apps for all four major U.S. networks are now included in universal search, as well as iTunes, Netflix, Hulu, HBO, Disney's suite of TV channels, Showtime, PBS, Starz, Nat Geo, and FX. In most other countries, only iTunes content is currently supported, while Netflix is also supported in Australia, Canada, France, Germany, and the United Kingdom.
