#7 – Dreamcast
The Sega Dreamcast was released in 1999, and was a predecessor to the Xbox, GameCube and the PlayStation 2. When it was released it was seen as the best gaming system available, and had a very successful launch and excellent sales. However, upon Sony’s release of the PlayStation 2, Sega was unable to compete. The PlayStation 2 was able to play DVD movies, something the Dreamcast was unable to do. Without enough money to advance the technology, Sega discontinued the Dreamcast in 2001, and has never attempted to release a gaming system since.
