Nobody needs to watch TV news.
Okay, I don’t want to judge. Maybe not nobody per se, but I can’t think of anyone who should. Reading the news gives you far more information and a more detailed image. If someone has bad eyesight, then radio news (not talk radio, of course) or podcasts are better.
TV news is entertainment. I’m talking about 24 hour news channels, broadcast news, and even local news. If you want to watch something then check out C-SPAN or watch a documentary.
