The Dallas Cowboys have unseated Spanish football club Real Madrid for top spot on a list of the world's 50 most valuable sports teams, according to a Forbes poll that was dominated by NFL franchises.
The value of the National Football League's Cowboys rose 25 percent to $US 4 billion compared to last year, while the value of 10-time European champions Real Madrid rose 12 percent to $US 3.65 billion over the same period, Forbes said in a statement.
It marks the first time since the list's inception in 2011 that a non-football club has taken the top spot on the list.
"Blockbuster TV contracts are fuelling unprecedented increases in sports team values around the globe as the average value of a top 50 franchise has doubled over the past four years," said Forbes senior editor Kurt Badenhausen.
"The NFL is still king on TV with contracts worth nearly $US 7 billion annually from its media partners."
Soccer's Barcelona ($US 3.55 billion), Major League Baseball's New York Yankees ($US 3.4 billion) and Manchester United ($US 3.32 billion) rounded out the top five.
The NFL had 27 franchises listed in the top-50 followed by European soccer and the National Basketball Association, who each had eight teams on the list, followed by MLB with seven.
