It was renamed Real World/Road Rules Challenge for the 2nd season, then later abridged to simply The Challenge by the show's 19th season. The show was originally titled Road Rules: All Stars (in which notable Real World alumni participated in a Road Rules style road-trip).
The winners of the final challenge win the competition and typically share a large cash prize. The contestants compete against one another in various extreme challenges to avoid elimination. Originally featuring alumni from these two shows, casting for The Challenge has slowly expanded to include contestants who debuted on The Challenge itself, alumni from other MTV franchises including Are You the One?, Ex on the Beach ( Brazil, UK and US), Geordie Shore and from other non-MTV shows. The Challenge (originally known as Road Rules: All Stars, followed by Real World/Road Rules Challenge) is a reality competition show on MTV that is spun off from two of the network's reality shows, The Real World and Road Rules.
