The TurboGrafx-16 is one of the more underrated video game consoles. It was released around the same time as the Sega Genesis and had roughly the same capabilities. Like the Genesis, a CD add-on was developed for the TurboGrafx-16. The TurboGrafx-16 took it one step further and later released an enhanced all-in-one unit called the Turbo Duo and on the whole had far better CD software than the Genesis/Sega CD did. There was even a portable TurboGrafx-16 called the Turbo Express. Technically impressive but not all games were reasonable on the small screen and battery life was not so great.
The real killer as far as the TurboGrafx-16 is concerned is the same as all systems who die a premature death. Lack of software. While there were many impressive titles available in Japan and the console was very successful there, the same can not be said of U.S. releases. Far fewere games were released and the Japanese and U.S. divisions did not work well together.
The above commercial is dated 1991 but must have come out before the Duo was announced later in the year because it isn't featured. However, you do get glimpses of the TurboGrafx-16, Turbo CD and Turbo Express as well as some of the games.
