"That's my point here. If you removed PlayStation, the third party games would still exist on other platforms and the growth that was achieved by the PS1 would have been achieved by other console manufacturers. And the software that was put out by third parties wouldn't have really changed because the seeds for what was made in the fifth generation were already planted during the middle of the fourth generation."
And what company would that have been? Toyota? Canon? Lets list all the big conglomerates who failed to make a gaming console that expanded gaming before Sony and the playstation:
Asia:
Panasonic (formally Matsushita Electric), Sanyo, LG with the 3DO, released...1 year before the Playstation
NEC
US:
All American manufactures dropped out with the video game crash of the 80s and Atari was on its last legs as a console manufacturer
Europe:
Phillips with the CD-i
Sony was one of the only ones left and the one with the best chance as they pretty much mirrored Nintendo since the mid 80s. They understand the videogame console market better than all the above.
