I watch some of the video generated by the Maddon football video game, and find it almost as realistic as the real games. Someday, some entrepreneur is going to figure out that you can have realistic pro games generated by software. It will save a lot on player salaries etc. Then when the people at home start watching those instead of the real games (maybe they will all be online, and not blocked by the networks), they might not even want any more to go see real games at the stadium.
