Sega CD
The CD-ROM drive that bolted onto the Genesis, full-motion video, Night Trap and 2.24 million sold
The Sega CD (Mega-CD outside North America) was a CD-ROM add-on for the Sega Genesis, released in Japan on 12 December 1991 and in North America on 15 October 1992 at $299. It added a faster CPU, scaling and rotation hardware and CD audio, and became known for full-motion-video games such as Night Trap and Sewer Shark alongside Sonic CD and Lunar. About 2.24 million were sold before Sega discontinued it in 1996 for the Saturn.

Why it shut down [edit]
Official line: Sega discontinued the Sega CD in early 1996, after about 2.24 million units, to concentrate on the Saturn. The add-on had cost $299 at its October 1992 American launch, more than the Genesis it plugged into, and its library leaned on grainy full-motion-video games that dated within a year; Sega's own 32X, launched in 1994, split what was left of the market for Genesis add-ons.
Our analysis: The Sega CD was an early answer to a real question, what CD-ROM could do for games, and it got the answer wrong: video. Its best games, Sonic CD, Lunar, Snatcher, used the disc for music and space; most of the rest used it for blurry film clips in a small window. It was expensive, it was an add-on, and Sega followed it with another add-on and then a new console within three years, teaching Genesis owners not to trust the company's roadmap. That lesson carried into the Saturn.
History [edit]
A disc under the Genesis
Sega of Japan built the Mega-CD to keep the Mega Drive competitive with the PC Engine CD-ROM and NEC. It launched in Japan on 12 December 1991 at 49,800 yen: a drive unit that sat under the console with its own 12.5 MHz 68000 processor, more RAM, a graphics chip for the scaling and rotation effects the Genesis lacked, and CD-quality sound. North America got it as the Sega CD on 15 October 1992 at $299, only 50,000 units at launch because of production limits, and it sold 200,000 by the end of the year. Europe followed in April 1993, and a cheaper, top-loading second model came in 1993.
The launch line-up was Sewer Shark and Night Trap, both built on grainy full-motion video, and that set the tone. Night Trap became the exhibit in the 1993 US Senate hearings that led to the ESRB. The games that used the disc well, Sonic CD (September 1993), Lunar: The Silver Star, Lunar: Eternal Blue, Snatcher, Popful Mail, Final Fight CD, showed what it could do; the majority did not.
Overtaken by Sega itself
Sales stalled in 1994 as Sega launched the 32X, another Genesis add-on, and announced the Saturn. The Sega CD 32X combo games were the low point. Sega ended production and support in early 1996, having sold about 2.24 million units worldwide, and moved on to the Saturn, which itself lasted only two more years in the West. The Sega CD library survives on Genesis Mini 2 and in Sonic Origins, and Night Trap got a 25th-anniversary re-release in 2017.
