The Philips CD-i (an abbreviation of Compact Disc Interactive) is an interactive multimedia CD player developed and marketed by Dutch company Philips, who supported it from December 1991 to late 1998. It was created to provide more functionality than an audio CD player or game console, but at a lower price than a personal computer with a CD-ROM drive.  "CD-i" also refers to the multimedia Compact Disc standard used by the CD-i console, also known as Green Book, which was co-developed by Philips and Sony.
