The Compact Disc-Interactive (CD-I, later CD-i) is a digital optical disc data storage format as well as a hardware platform, co-developed and marketed by Dutch company Philips and Japanese company Sony. It was created as an extension of CDDA and CD-ROM and specified in the Green Book specifications, co-developed by Philips and Sony, to combine audio, text and graphics.[2] The two companies initially expected to impact the education/training, point of sale, and home entertainment industries,[3] but the CD-i is largely remembered today for its video games.

CD-i media physically had the same dimensions as CD, but with up to 744 MB of digital data storage, including up to 72 minutes of full motion video.[4] CD-i players were usually standalone boxes that connect to a standard television; some less common setups included integrated CD-i television sets and expansion modules for personal computers.[5] Most players were created by Philips; the format was licensed by Philips and Microware for use by other manufacturers, notably Sony who released professional CD-i players under the "Intelligent Discman" brand. Unlike CD-ROM drives, CD-i players are complete computer systems centered around dedicated Motorola 68000-based microprocessors and its own operating system called CD-RTOS, which is an acronym for "Compact Disc – Real Time Operating System".[6][7][8][9]

Media released on the format included video games and "edutainment" and multimedia reference titles, such as interactive encyclopedias and museum tours – which were popular before public Internet access was widespread – as well as business software.[10] Philips's CD-i system also implemented Internet features, including subscriptions, web browsing, downloading, e-mail, and online play.[11] Philips's aim with its players was to introduce interactive multimedia content for the general public by combining features of a CD player and game console,[4] but at a lower price than a personal computer with a CD-ROM drive.

Authoring kits for the format were released first in 1988, and the first player aimed for home consumers, Philips's CDI 910/205, was released in late 1991. It was initially priced around US$1,000 (equivalent to $2,237 in 2023),[12] and was capable of playing interactive CD-i discs, Audio CDs, CD+G (CD+Graphics), Photo CDs and Video CDs (VCDs), though the latter required an optional "Digital Video Card" to provide MPEG-1 decoding. Initially marketed to consumers as "home entertainment systems", and in later years as a "gaming platform",[2] CD-i did not manage to find enough success in the market, and was mostly abandoned by Philips in 1996.[13][14] The format continued to be supported for licensees for a few more years after.[15]
