Atari's first hired artist, George Opperman, explained the logic behind his 1972 creation, the iconic "Fuji" Atari logo:
“George tells us that the corporate logo basically represents a stylized letter ‘A’ to stand for ‘Atari.’ He did have an added inspiration in designing the symbol, though. Back in 1972, Atari’s claim to fame was ‘Pong,’ and George says the two side pieces of the Atari symbol represent two opposing video game players, with the center line of the ‘Pong’ court in the middle.”
