ESPN 2 used to cover FIRST back in the day.... I'm still not sure why they stopped. It would be nice to have a more mainstream coverage again though, and I know I wasn't the only extremely frustrated person over the SoCal regional last year when it came down to the last match, and NASA cut it off to sleeping astronauts!
Maybe Disney could give us a hand in this. They do have an amazing number of mainstream tv networks... ABC, Disney Channel, and ESPN I do believe...
