- 38 Seasons
In the game show series The Challenge, alumni of various MTV reality series compete against each other. They need to complete tasks, win prizes and advance toward the overall season championship. Originally featuring alums of MTV's The Real World and Road Rules, the series has expanded to include contestants from other shows. They include the UK's Geordie Shore, Big Brother, Ex on the Beach and The Challenge itself. The new version of the series is called The Challenge: Double Agents. In this version, a complicated system of rules includes a team of "Double Agents," the contestants who win the first round. After that, the other contestants battle to see who will win. They go through a series of eliminations, nominations, tribunals, twists, voting, gender challenges, and trophy presentations. Somehow, out of all of that, a winner is chosen. In later seasons of The Challenge, participant shows have expanded beyond the slate of programs on MTV alone. This season of The Challenge includes alumni of shows such as The Real World, Road Rules, The Challenge, Are You the One?, Big Brother, Celebrity Big Brother, Celebrity Big Brother UK, The Amazing Race, Survivor, Geordie Shore, Ex on the Beach (U.S.), Shipwrecked, America's Got Talent, WWE NXT, and Ultimate Beastmaster.
