In July 1971, Coca-Cola unveiled their iconic "I'd Like to Buy The World a Coke" advertising campaign in the United States with their iconic "Hilltop" television commercial. The jingle that was used in the commercial was a re-written version of Susan Shirley's song, "I'd Like to Teach the World to Sing (In Perfect Harmony)". After the first airing of the commercial, the song became so popular that two new versions of the song were released, and became a hit record in the United States and the United Kingdom.
