just entertainment? Aton of people just watch sports to shout at the TV (or field) and drink beer. A lot more than are genuinely interested in the physical performance.

And really, we absolutely glorify entertainment in our society. People look up more to Kim Kardashian or a Will Smith than a king. Athletes also but more because they bring in the "win" which is more entertainment. It's all about making you feel good about winning or the chance of it, and the Idea that you're part of it.
