|The Challenge is a reality game show on MTV that is spun off from and mostly cast-contestant dependent on the network's two flagship reality shows, The Real World and the now cancelled Road Rules. The Challenge has developed a spin-off series in its own right, Spring Break Challenge. The Challenge and Spring Break Challenge have a somewhat cast-contestant interdependent relationship in that both programs have used at least one or more contestants from the other. The Challenge is hosted by T. J. Lavin.
The series premiered on June 1, 1998. The title of the show was originally Road Rules: All Stars before it was renamed Real World/Road Rules Challenge by the show's 2nd season, then later abridged to simply The Challenge by the show's 19th season. The series initially used no hosts but instead a former cast member who had been kicked off his or her season, providing assignments as "Mr." or "Ms. Big". Later on, however, the series began using hosts: Eric Nies and Mark Long co-hosted a season, and Jonny Moseley and Dave Mirra hosted various seasons before T. J. Lavin became the show's regular host by the 11th season.
