The CDTV (an acronym for "Commodore Dynamic Total Vision", a backronym of an acronym for "Compact Disc Television", giving it a double meaning) was a multimedia platform developed by Commodore International and launched in 1991. It was the first game console and computer with a CD-ROM drive built in, released in March 1991.[citation needed]

Description[edit]

CDTV was essentially a Commodore Amiga 500 home computer with a CD-ROM drive and remote control. With the optional keyboard, mouse, and disk drive, it gained the functionality of the Amiga.[1] Commodore marketed the machine as an all-in-one home multimedia appliance in a home stereo-like case rather than a computer. As such, it targeted the same market as the Philips CD-i. Unfortunately for both Commodore and Philips, the expected market for multimedia appliances did not materialise, and neither machine met with any real commercial success. Though the CDTV was based entirely on Amiga hardware it was marketed strictly as a CDTV, with the Amiga name omitted from product branding.

Commodore announced the CDTV at the summer 1990 Consumer Electronics Show in Chicago, promising to release it before the end of the year with 100 software titles.[1] The product debuted in North America in March 1991 (CES Las Vegas) and in the UK (World of Commodore 1991 at Earls Court, London).[2] It was advertised at £499 for the CDTV unit, remote control and two software titles.[3] The device was released in the United States for $999.[4]

Commodore by 1990 had a poor reputation among consumers and developers. Computer Gaming World wrote that year of its "abysmal record of customer and technical support in the past".[1] The company chose Amiga enthusiast magazines as its chief advertising channel, but the Amiga community on the whole avoided the CDTV in the expectation of an add-on CD-ROM drive for the Amiga,[5] which eventually came in the form of the A570. This further hurt sales of the CDTV, as both it and an A570-equipped A500 were the same electronically, and could both run CDTV software, so there was very little motivation to buy it. Commodore would rectify this with CDTV's successor, the A1200-based Amiga CD32, by adding the Akiko chip. This would enable CD32 games to be playable only on the CD32.

The CDTV was supplied with AmigaOS 1.3, rather than the more advanced and user-friendly 2.0 release that was launched at around the same time. Notably, the CDXL motion video format was primarily developed for the CDTV making it one of the earliest consumer systems to allow video playback from CD-ROM.

Though Commodore later developed an improved and cost-reduced CDTV-II it was never released.[6] Commodore eventually discontinued the CDTV in 1993 with the launch of the Amiga CD32, which again was substantially based on Amiga hardware (in this case the newer Amiga 1200) but explicitly targeted the games market.

Design[edit]

The CDTV was intended as a media appliance rather than a personal computer. As such, its housing had dimensions and styling compatible with most stereo components, and it came with an infrared remote control. Similarly, it was initially sold without keyboard and mouse (which could be added separately, and were later bundled with the machine). The CDTV was based on the same technology as earlier Amiga systems, but featured a single-speed CD-ROM drive and no floppy disk drive as standard.
