The Super Bowl television rights are rotated on a three-year basis between CBS, Fox, and NBC. In 2011, all four stations signed new nine-year contracts with the NFL, each running until 2022; CBS, Fox, and NBC are estimated by "Forbes" to pay a combined total of US$3 billion a year, while ESPN will pay US$1.9 billion a year. The league also has deals with Spanish-language broadcasters NBC Universo, Fox Deportes, and ESPN Deportes, which air Spanish language dubs of their respective English-language sister networks' games. The league's contracts do not cover preseason games, which individual teams are free to sell to local stations directly; a minority of preseason games are distributed among the league's national television partners.
