Pong is the second video game ever created, the first being "Tennis for Two." It was designed by Atari Inc. and released on November 29, 1972. The name is derived from the action of imitating ping-pong.
Pong has entered popular culture as a term connoting something that in its heyday was quite popular, but with time has become outmoded. The game is still popular with Atari purists, and the original consoles and equipment often sell for hundreds of dollars on eBay, and other sites.
