The year 2000 brought heightened interest in the AFL. Then-St. Louis Rams quarterback Kurt Warner, who was MVP of Super Bowl XXXIV, was first noticed because he played quarterback for the AFL's Iowa Barnstormers. While many sports commentators and fans continued to ridicule the league, Warner's story gave the league positive exposure, and it brought the league a new television deal with TNN, which, unlike ESPN, televised regular season games live. While it was not financially lucrative, it helped set the stage for what the league would become in the new millennium. Also, the year also brought a spin-off league, the AF2, intended to be a developmental league, comparable to the National Football League's NFL Europe. There was a lot of expansion in the 2000s. Expansion teams included the Austin Wranglers, Carolina Cobras, Los Angeles Avengers, Chicago Rush, Detroit Fury, Dallas Desperados, Colorado Crush, New Orleans VooDoo, Philadelphia Soul, Nashville Kats, Kansas City Brigade, New York Dragons and Utah Blaze. Some of these teams, including the Crush, Desperados, Kats, and VooDoo, were owned by the same group which owned the NFL teams in their host cities. The NFL purchased, but never exercised, an option to buy a major interest the AFL. Of all of these teams, only the Soul still compete in the AFL as of now.
