After the turmoil in the 1980s, the NFL decided to form its own league in 1991, the World League of American Football, as a spring developmental league. For the first time, an American sport league had a European division as part of its ten-team league, while the other teams were located in continental US and Canada. The league was used to test rule changes and technical innovations and planned as a farm system for NFL teams. However, the first two seasons produced low TV ratings, and the league was put on hiatus until 1995. When it came back, the league was based entirely in Europe, reduced to six teams, and re-branded in 1998 as NFL Europe. The league kept the same format until 2007, when the NFL terminated it. Ultimately, the league was one of the longest tenured high-level minor leagues in history, lasting fifteen years in total and producing players like Hall of Famer Kurt Warner and Super Bowl quarterbacks Brad Johnson and Jake Delhomme. Other notable players include Dante Hall, David Akers, James Harrison, Adam Vinatieri, and William Perry.
