In 2000, Woody Johnson bought the Jets for $635 million. Since then, the team has doubled in value, according to Forbes.
The Jets are worth $1.23 billion, ranking 12th on the magazine's list of the 50 most valuable sports franchises in the world.
Four NFL teams are ranked ahead of the Jets -- the Cowboys (No. 3 overall, tied with the Yankees at $1.85 billion), Redskins (No. 4, $1.56 billion), Patriots (No. 6, $1.4 billion) and Giants (No. 9, $1.3 billion).
In case you're wondering, Manchester United tops the list at $2.23 billion. Johnson, who recently slashed ticket prices, will have to sell a lot more club seats before he approaches that number.
