There are two 24hr all sports network on my cable system. Throw in the Fox sports network, and MSG, and that's a lot airtime to fill; however, in recent years, I don't remember seeing a single bodybuilding show on any of these networks.
If bodybuilding has these "million" of practioners, you think it would be profitable to televise it. The reality is that bodybuilding and fitness are two different animals. Just because more people are working out in gyms, or more accurately, health clubs, in no way does it mean that "bodybuilding" is more popular today.
In 2006, how many bodybuilding contests do you think will be broadcast on either ESPN, or ESPN2?
My guess would be: Zero.
