Re: Selig extended through 2012
The Wild Card has helped a lot. It allows more teams to get into the playoffs, which means increased interest when teams would have been out of it before. Do you think 1999 would have been the same had the WC not existed? There have been many many teams that are now able to compete because of the WC system. With up to 14-16 teams that are still in the race until late Sept every year, that's a huge boost to attendance and interest in baseball.
Interleague has also greatly boosted attendence and has been very good for clubs. I'm getting tired of it, but just about any Reds/Indians is nearly sold out. Along with all the other typical matchups, and any team facing the Yanks/Sox.
