How the economy has affected sports.

Fast fact: General Motors has spent $77.1 million on Super Bowl advertising in the last 15 years. The corporation announced in September that it will not purchase any commercial time during the 2009 game.

This and lots of other nuggets can be found in the Oct. 13 issue of Sports Illustrated in a story titled "Money Changes Everything," which examines the impact the down economy is having on the sports market.

Just to underscore the whole rich-get-richer trope, the story reports that none of the luxury boxes — priced at $650,000 to $850,000 per season — in the new Yankee Stadium will be empty when it opens next season.
