Dreamcast
The Dreamcast is perhaps one of the most interesting console flops of all time.The Dreamcast only sold 10.6 million units, including units sold after the Dreamcast was discontinued, and forced Sega to struggle through significant financial losses. The Dreamcast actually had many of the features that successful consoles often boast — good games, impressive power and innovative hardware like the VMU. While there were quite a few things credited with causing Sega’s console flop, like poor advertising and some friction with EA, the console’s innovation actually seemed to play a part in its lackluster sales.
The Dreamcast’s online capabilities couldn’t really be supported by the limited broadband access that was available at the time. So while the Dreamcast was praised as one of the best products of 1999 by BusinessWeek, it couldn’t convert its massive potential, power, and innovation into actual sales.
