As with 4K, it's now hard to buy a TV that doesn't have a smart platform packed with streaming apps. Almost every TV will have Netflix and Amazon Prime Video on board, and Disney+ is fast approaching a similar level of ubiquity. Apple TV (which is great for pay-as-you-go movies as well as the Apple TV+ subscription service) is becoming increasingly common, too.
You'd have thought that BBC iPlayer, ITV Player, All 4 and My5 would be present on every TV available in the UK, but there always seems to be one brand that's lacking (it was LG in 2020 and Sony in 2021) so do check before you buy if any of those are important to you.
Other apps that are less common but potentially worth looking out for include BT Sport, Now, Britbox, and music apps such as Spotify and Tidal.
