Why did Commodore Amiga and Atari go bankrupt while PC's were so boring in comparison?
There are many reasons, but one reason is that while the PC
catered to the business segment, gaming consoles were on the rise
in the early nineties. Multimedia computers simply failed to
compete in either market and fueled by large sales in the 1980's
Commodore and Atari had very ambitious and costly development
projects.
Also, the advent of 3D gaming proved difficult for the Amiga and
Atari computers. While PCs had chunky bitmaps that made texture
mapping easier, the bitplane design graphic subsystems made it much
harder to program 3D games. PCs also had an edge with raw
processing power required for geometry processing.
Take it as a lesson, success is an ongoing process, and markets
change rapidly.
