It's a little-known fact that some major sports teams are part-owned by public companies. While owning shares in the teams won't get you any perks, it would be sweet to say "I own a little piece of the Steelers."
Unfortunately, you can't invest in the greatest football team in the U.S., but there are other strong names you can get a stake in:
Boston Red Sox
The New York Times
New York Knicks and New York Rangers
The owner of both teams as well as the eponymously named sports arena Madison Square Garden
Daytona International Speedway and Talladega Superspeedway
While not owning any teams, International Speedway
Owned by Walt Disney
Sirius XM Radio
One of the largest draws for Sirius XM's 19.5 million subscribers is the company's agreements with the NFL and NASCAR that let subscribers listen to live coverage of every game and event. While both these agreements expire in 2011, sports will continue to play an important role in Sirius XM's business.
