Linear TV won't be going anywhere for a while.

Traditional means of broadcasting them (over the air, satellite) may go in favour of IP based streaming, but they'll still be around.

I'd like to think that you'll see fewer channels with better quality, acting as shop windows for streaming services like ITVX etc, but in reality, you'll likely see an explosion of linear style channels as we're seeing with Samsung TV Plus, Pluto, Peacock etc.
