I agree, but spectator entertainment isn't going anywhere, because people will always look and listen. Movies, TV, radio, and all their evolved tech mediums will survive to an extent (and that includes books on tape and newspapers online). But spectator sports will also be in the mix, as they have since probably before Colosseum gladiators competed for attention with actors in plays.
After all, beside sports, what other diversion exists where even adults can cheer, swear, jump up and down, hug and high five, and throw things in anger and/or jubiliation?
