"Turn It On Again" is a song by the English rock band Genesis featured on their 1980 album Duke. Also released as a single, the song reached number 8 in the UK Singles Chart, becoming the band's second top 10 hit. The lyrics, by Mike Rutherford, concern a man who does nothing more than watch television. He becomes obsessed with the people he watches on it, believing them to be his friends.

Duke is the tenth studio album by English rock band Genesis, released on 28 March 1980 on Charisma Records. The album followed a period of inactivity for the band in early 1979. Phil Collins moved to Vancouver, Canada, in an effort to salvage his failing first marriage, while Tony Banks and Mike Rutherford recorded solo albums. Collins returned to the UK after his marriage ended and wrote a significant amount of material, some of which was used for Duke and some was later reworked for his first solo album, Face Value. Duke contained a mix of individually written songs and tracks that evolved from jam sessions in mid-1979, while recording took place at the end of the year. The break in activity rejuvenated the band, and they found the album an easy one to work on.
