The Dallas Cowboys haven't won big in 30 years. Or have they?

The Dallas Cowboys have not reached the NFC Championship in 30 years. But their lack of on-field success has not hindered their popularity and profits.

On a Hollywood red carpet last week, Jerry Jones, the owner of the NFL's Dallas Cowboys, was asked about his team's upcoming season.

“If we get that offensive line rolling,” Jones told an interviewer, “we’ll have a good team.”

What counts as a "good" season is more subjective in Dallas than anywhere else — and it's why, ever since Jones purchased the team for $140 million in 1989, there has been no other North American professional sports franchise quite like the Cowboys.

Since they won Super Bowls in 1992, 1993 and 1995, the Cowboys have not advanced to a conference championship game in 30 years, the fourth-longest active drought in the NFL. That lack of on-field performance would typically doom a franchise's relevance.

Not the Cowboys.
