"Roundball Rock" is a theme song composed by John Tesh and used for The NBA on NBC from 1990 until 2002. NBC played the song 12,000 times during their run. Tesh came up with the melody while at a hotel and called his answering machine at home to play a preliminary version of the melody so he would not forget it. A more rock-oriented variant was introduced in 1997, to coincide with the debut of the WNBA; that theme was also used until 2002, and on NBC's WNBA telecasts only.
When ABC took over broadcasting rights for the National Basketball Association (NBA) from NBC, Tesh offered them the rights to also use his song, but they declined and chose to compose their own theme music instead.
