There has already been a good bit of unbundling in television, but it's important to remember that live sports is the most important content for television. In 2023, live sports accounted for 96 of the 100 most-watched shows on US television and I am pretty sure 2024 was no different. Will that be over the air (ABC, NBC, etc.) or streaming? Does ABC really care how I receive their content? If they can continue selling ad time to support their over the air programming, they will thrive. I believe there is a good argument that networks (ABC, NBC, etc.) could disappear if all sports goes to subscription streaming. But, I don't see that happening soon.
Just look at the fallout at the Washington Post. As their content creators are leaving the Post, subscribers are canceling subscriptions. The same will happen with TV. If the networks no longer have sports, people will quit watching and the advertisers will migrate to the subscription services. You have to have desirable content.
