CD+G (also known as CD-G, CD+Graphics, and TV-Graphics) is an extension of the compact disc standard that enables the display of low-resolution graphics alongside audio content when played on a compatible device. This functionality is most commonly associated with karaoke systems, which use CD+G discs to display on-screen lyrics synchronized with music playback. The CD+G format was defined by Philips and Sony as an extension of the Red Book specification for audio CDs.
The first commercially released CD to utilize the CD+G format was Eat or Be Eaten by Firesign Theatre in 1985. A related format, CD+EG, offers enhanced graphical capabilities but has seen little adoption in commercial releases.
