ESPN’s Apple TV app has been upgraded to include a new MultiCast feature that allows users to view up to four streams at the same time, according to Variety. EPSN typically features 30 or more live events on a given day, all of which will be available for simultaneous viewing. The company has also released an update to its iOS app, adding a “Watch” tab that provides live streams of events and shows. In other tvOS app news from Variety, Walmart’s streaming service will be landing on Apple TV next week. While Apple TV users have previously been able to use AirPlay to play Vudu’s movies and TV shows, the dedicated Vudu app is expected to become “widely available” starting August 22.
