I mean it seems to me all is saying it's that instead of having a separate app for BBC, ITV, C4 it'll all be under one app for when you want to stream live programmes. But I honestly can't remember the last time I watched a live programme, so will still be using the separate apps to watch stuff on catch-up.

Britbox is actually pretty decent to find old things on, but the smart TV app interface is rubbish.
