Forbes released its 2013 list of the 50 Most Valuable Sports Teams.  Among the 50, Real Madrid, the New York Yankees, Dallas Cowboys, New York Knicks and Toronto Maple Leafs ranked as the best-earning franchises in their respective sports. 

Real Madrid topped the list with a value of $3.3 billion.  The club earned $650 million during the 2011-12 season, which was the highest revenue in sports during that time.  Annual deals with Adidas and Emirates Airlines added a combined $80 million. 

Manchester United ($3.165 billion) and Barcelona ($2.6 billion) ranked second and third on the Forbes list. 

The New York Yankees were the most valuable U.S. sports franchise.  The team's value of $2.3 billion earned it the No. 4 spot on the list.  The franchise sold part of its interest in the YES Network when Fox purchased 49 percent of the regional sports network in 2012.  The rights fee from YES increases to $85 million this season, and it will reach $350 million in 2042, according to Forbes.

The Dallas Cowboys ranked No. 5 on the list, making the franchise once again the most lucrative team in the NFL with a value of $2.1 billion.   The team has been the NFL's most valuable club since 2007.  Robert Kraft's New England Patriots followed at No. 6 with $1.635 billion.  

MLB's second most valuable club was the Los Angeles Dodgers.  The Dodgers' value of $1.615 billion put them at No. 7 on the list.  A 25-year deal with Time Warner Cable is close to completion, which could earn the Dodgers close to $8.5 billion annually.

NFL teams dominated the list from there.  The NBA's most valuable franchise this year was the New York Knicks.  The team's $1.1 billion topped the Los Angeles Lakers, who ranked No. 31 with $1 billion.

The NHL's only team to make the list was the Toronto Maple Leafs, who tied with the Lakers for the No. 31 spot.
