PBS is available on all kinds of mediums. They have apps on Apple's App store, they have apps on Apple TV, and you can stream content from their web site(s). And not only new programs, but amazing archives of old content as well. Want to relive your childhood of watching Mr. Rogers? It's all there, it's all free, and it's available via a bunch of access methods! So rather than choosing Youtube TV, they seem to be embracing a "all possible mediums" strategy. The only down side is that you need to get around the location check. Pretty great for free if you ask me. I'm surprised all their stuff isn't on Netflix to be honest, since it's just about everywhere else.
