season 15. Season 14 was the final season of the series to air on Spike, who considered the relationship to be "incredibly beneficial in building both our brands.” In September 2013, the series moved to Fox's new mainstream sports network Fox Sports 1. Because of the need to keep the fight results secret until the airing of the episode, each fight on The Ultimate Fighter is officially an "exhibition", and as such does not count towards the fighters overall record. Selection process Seasons 1–4 For the first four seasons, prospective UFC fighters from two different weight classes were selected to compete. The fighters are divided into two teams, irrespective of weight class, with each team coached by a current UFC headliner. The teams then compete (in a manner which varies by season), with the loser being eliminated from the competition. Often, incentives are provided for the team of a winning fighter.

The show features the daily preparations each fighter makes to train for competition at the UFC training center, and the interactions they have with each other living under the same roof. Day-to-day events on the show are overseen by UFC president Dana White.

Though officially exhibition fights, the UFC chooses to record the results of semi-final matchups. For example, the seventh season winner Amir Sadollah has one more win on his UFC
