Dreamcast

The Dreamcast^[a] is the final home video game console manufactured by Sega. It was released in Japan on November 27, 1998, in North America on September 9, 1999, in Europe on October 14, 1999 and in Australia on November 30, 1999. It was the first sixth-generation video game console, preceding Sony's PlayStation 2, Nintendo's GameCube, and Microsoft's Xbox. The Dreamcast's discontinuation in 2001 ended Sega's 18 years in the console market.

A team led by Hideki Sato began developing the Dreamcast in 1997. In contrast to the expensive hardware of the unsuccessful Saturn, the Dreamcast was designed to reduce costs with off-the-shelf components, including a Hitachi SH-4 CPU and an NEC PowerVR2 GPU. Sega used the GD-ROM disc format to avoid the expense of DVD licensing. To speed game development, the console could run a custom version of Windows CE for easier PC game porting and shared hardware with Sega's NAOMI system board enabled arcade game conversions. The Dreamcast was the first console to include a built-in modular modem for internet access and online play.

Though its Japanese release was beset by supply problems, the Dreamcast had a successful US launch backed by a large marketing campaign. However, sales steadily declined as Sony built anticipation for the PlayStation 2. Dreamcast sales did not meet Sega's expectations, and attempts to renew interest through price cuts caused significant financial losses. After a change in leadership, Sega discontinued the Dreamcast on March 31, 2001, withdrew from the console business, and restructured itself as a third-party developer. A total of 9.13 million Dreamcast units were sold worldwide and over 600 games were produced. Its bestselling game, Sonic Adventure (1998)—the first 3D game in Sega's Sonic the Hedgehog series—sold 2.5 million copies.

The Dreamcast's commercial failure has been attributed to several factors, including competition from the PlayStation 2, limited third-party support, and the earlier failures of the 32X and Saturn having tarnished Sega's reputation. In retrospect, reviewers have celebrated the Dreamcast as one of the greatest consoles. It is considered ahead of its time for pioneering concepts such as online play and downloadable content. Many Dreamcast games are regarded as innovative, including Sonic Adventure, Crazy Taxi (1999), Shenmue (1999), Jet Set Radio (2000), and Phantasy Star Online (2000). The Dreamcast remains popular in the video game homebrew community, which has developed private servers to preserve its online functions and unofficial Dreamcast software.
