Anyone remember "Pong"?

It was the first commercially successful video game.

Manufactured by Atari in 1972.

Two-dimensional graphics.

Now for what you may not have known, via the NYT blog Bits:

The first Pong system was installed at a Sunnyvale, Calif., bar called Andy Kapps, which used to be the site of the first bus stop in the city. The lines to play the game would stretch out the door, and the system had to be shut down often to clear out the coins blocking the over-filled payment slot. Today, the site is host to the Rooster T. Feathers comedy club.
