Here's some data via FOX Sports. I apologize for the big graphics. I've included some ratings info, which clearly shows when it comes to sports All-Star events, baseball is still at the top.
They also created a couple of fun charts comparing life in 1989 (the last time the MLB All-Star Game was in Anaheim) to life in 2010. Baseball's top salary has increased by nearly 14x, and the average salary has increased nearly 7x. Many things have doubled, tripled or more in pricing, but the In-N-Out Burger is only up $.40, a scant 32% increase!
Not included in the tale of the tape: the 1989 game, which aired on NBC had an 18.2/33 household/share. In the 1988-89 TV season the exodus from broadcast to cable was still well under way. That season only 7.5% of the viewing in primetime was for advertiser supported basic cable. Last season (2008-09) basic cable snared 36.3% of primetime viewing.
