I would go so far as to say that the criticisms of broadcast television were completely correct; and that for all the problems of modern centralized social media and other internet use, one major good thing that it has done is kill off broadcast television. It is much easier now than it was for much of the 20th century for random ordinary people who weren't members of established mass media organizations to broadcast their ideas to the world, and try to build an audience that cares about their message. And even though this results in a lot of bad content being made (or just content that is uninteresting to you personally), it also allows a lot of gems to rise to people's attention that never would have under the old mass culture making system.
