you're correct, but there's a lopsided concentration of capital and political authority vested in very elderly people who have very little inclination in keeping up with twitter memes and would instead rather listen to Hannity and Tucker Carlson

Carlson regularly has an audience of 4.5 million+ tune into every show he does. Just for comparison, the most watched Twitch stream of all time peaked at 3.3 million. I remember reading a stat once (don't remember where) that if you regularly have just 20 viewers in a stream you're doing, you're in the top 1%. TV still has a very concentrated rapt audience, whereas the internet has far less focus.
