Deutschland sucht den Superstar is a German reality talent show. Part of the Idol franchise, it was created by British media mogul Simon Fuller as a spin-off from the British show Pop Idol, of which two series were broadcast between the years of 2001 and 2003. Debuting to mediocre ratings in November 2002 on the RTL network, the show has since become one of the most successful shows on German television.
