CD+G

CD+G (also known as CD+Graphics) is an extension of the compact disc standard that can present low-resolution graphics alongside the audio data on the disc when played on a compatible device. CD+G discs are often used for karaoke machines, which utilize this functionality to present on-screen lyrics for the song contained on the disc.

The first CD to be released with CD+G graphics was Eat or Be Eaten by Firesign Theatre in 1985.
