The best part of this is the channel doesn't pause when you flip away from it. It is always "running" and if you flip away you will miss it. That builds in a FOMO trade-off which causes user to automatically/subconciously decide on channel they most want to watch, because they can't watch everything.

I use Pluto for this. Quick download, no sign up required, and tons of topic-specific channels to switch to. I put it on all my devices and don't even worry about it.
Google TV also has a "Live" tab that collects all the live channels across all your apps and puts it into a TV guide grid. I've installed Fubo and Tubi and others just to build out my TV guide.
