People have so many more choices than when they wore fedoras to the game and listened on the radio. So much more than even the games in lively black and white, over the air, television. People are still entertaining themselves. Want to watch a movie? Stream it. Want to learn how to build a backyard pizza oven? Go on line and start gathering materials.
When there were six stations to watch, that baseball game may have been the best option. Now, with literally millions of things to look at, it might not be to the casual fan.
It's a crowded marketplace with business all fighting for your attention and time. Keep doing the same old stuff from fifty years ago and every time an octogenarian dies, so too does your business.
