Baseball's sales have increased 50 percent from 2004 and have doubled since 2000, CNN reported. DuPuy said that the level of growth this year had surprised even him and Commissioner Bud Selig.
“We have seen a healthy increase in every one of our revenue streams," DuPuy said. "We saw about a $0.5 billion from sources that really didn't exist 10 years ago."
DuPuy told CNN he expects revenue growth in the single digit percentage range in 2008 and an even bigger jump in revenue in 2009.
