I think attendance will take a long time to come back. That'll put a premium on TV sports. I imagine every league is going to try to put its games on in front of empty arenas. The Big 5 conferences, too. There will be even more money for the advertising because the audiences will be bigger. Think of it this way: all those Sunday afternoon baseball games during good weather? Remember how maybe you'd want to go to your kids soccer game, or go for a bike ride, or hit the farmer's market? Well, those options aren't going to be available. You will be a captive audience, and most everyone will want a break from the news.
