The use of personal seat licenses (PSLs) has become popular with teams in the NFL as an additional revenue stream, and even the Minnesota Vikings have admitted to the Pioneer Press that they are taking a "hard look" at introducing PSL fees to allow fans to guarantee the rights to specific seat for the new stadium planned to open in 2016.

The mechanics of a PSL are that the team sells the rights to buy season tickets for a particular seat in the stadium, and the PSL rights holder can then either buy season tickets in that spot or sell the license to someone else.

Many NFL teams have started to use PSLs in recent years. The Baltimore Ravens, Chicago Bears, Carolina Panthers, Cleveland Browns, New York Giants, New York Jets, Houston Texans, St. Louis Rams and Tennessee Titans all use some form of the PSL model.
