If AT&T was smart, they would ditch SD, ditch all the BS channels, and concentrate all their satellites into providing 4K and 8K. If they could get Fox Sports, NBC Sports and ESPN to opt in, along with some other popular channels, they could be the only 4K provider. With ATSC 3.0 coming out, they could even work out something with networks to allow them to provide the locals in HD, but switch the programming to 4K for major events in the same way they do with Thursday night football now. There are a LOT of people with 4K TV, and cable service with caps preventing them from streaming much of it. Programmers arent doing much 4K because there is no effective distribution channel.
