Atari
Atari was indeed the creator of pong, centipede and pacman. Many of us older folks would call it the beginning and "foundation of all video games". But alas, all things must come to a miserable end.
Atari has been having a horrible time trying to compete with much of anything since 2000, and Nintendo in 1980 already had a clear advantage in the field of innovation.
Atari had changed hands over three times in the past ten years. They were destined to fail, but rather than merge with the larger companies, they chose to cut their losses, and thus the American headquarters of Atari will never be heard from again.
It was nice knowing them. "Here today, gone tomorrow- Marcus Aurelius"
