During the SNES's life, Nintendo contracted with two different companies to develop a CD-ROM-based peripheral for the console to compete with Sega's CD-ROM based addon, Mega-CD. Ultimately, deals with both Sony and Philips fell through, (although a prototype console was produced by Sony) with Philips gaining the right to release a series of titles based on Nintendo franchises for its CD-i multimedia player and Sony going on to develop its own console based on its initial dealings with Nintendo (the PlayStation).
