Cowboys, Yankees tops as Forbes releases list of most valuable sports franchises

It's not an investment option open to many folks, but buying a pro sports franchise can pay off big time, and Forbes latest ranking of the top 50 sports teams in the world proves it. The Dallas Cowboys, with an estimated worth of $5 billion, top the list, followed by the New York Yankees, at $4.6 billion and Spanish soccer club Real Madrid, at $4.24 billion. While the teams represent multiple sports and cross international lines, NFL teams comprise more than half of the list, owing largely to lucrative television deals that bring each team upwards of $250 million per year.
