"Do They Know It's Christmas?" was a charity song created by the supergroup Band Aid in 1984 to raise funds for famine relief in Ethiopia, Africa. The song, written primarily by Bob Geldof and Midge Ure, included contributions from famous musicians such as Bono, Sting, Phil Collins, and Boy George. The release of the song marked the beginning of a new era of celebrity activism, and it became one of the biggest-selling singles of all time. The proceeds from the song were used to finance humanitarian work in Ethiopia and other parts of Africa.
