Three years of 8-8 seasons have done wonders for Jerry Jones' bottom line.

  Forbes magazine reports today that the Dallas Cowboys are the first U.S. professional sports franchise to be worth more than $3 billion.  Forbes puts the value of the team, which Jones bought from Bum Bright in 1989 for $140 million, at $3.2 billion.

  In fact, the Cowboys are the second most valuable professional sports franchise in the world, behind only Real Madrid of European Soccer.

  Number two in the NFL is the New England Patriots, with a value of $2.6 billion.  The Redskins and the Giants are both also worth more than $2 billion.

  Forbes values Jones' franchise based on its $245 million operating income for the last eyar, which is nearly double the second place Patriots.  Forbes says the Cowboys had more than $560 billion in total income last year.

  While the markets value the Cowboys, the fans do too.

  A new survey by the real estate blog Estately shows that the Cowboys are by far the most popular NFL team in the United States.

  The Cowboys rank far ahead of second place Philadelphia in the rankings of America's most popular pro football teams.

  The five most popular NFL franchises in Texas are the Cowboys, followed by the Texans, the Saints, the Eagles, the Broncos, and the 49ers.

  The least favorite football team in Texas and in the USA is the Jacksonville Jaguars.
