Apple has expanded universal search options for film and TV on standard Apple TV and Apple TV 4K. The additional options are country-specific, as the network offerings vary by country. In the US, Apple TV will now show listings from Classix, Oxygen, and BBC America, as long as you have the apps installed.

While the US is still the country with the most Apple TV listings, other countries are seeing expansion as well. Canada is getting Classix, FXNOW Canada, Treehouse, CBC TV, and ICI Tou.tv, among others. Norway and Sweden are getting Viaplay, while Australia is getting 9Now, Tenplay, and SBS listings. More countries are getting Apple Music search, too, including multiple European countries, Canada, Mexico, Australia, and Japan.
