Nintendo had the NES and SNES. Sony the PS1 and PS2. So Atari I guess. For the second question one would think for profit. The third I wouldn't know but I am going for Square. As for the fourth don't know. As for the last I only count consoles that are counted within a generation so Sony. But wasn't the Philips CD developed earlier.
Please excuse my (probally) poor grammar
