Pong Doubles © 1973 Atari.
A follow-up to the original Pong, Pong Doubles is essentially a four-player version of the original. Two players stand on each side of the dividing line, one in front, the other behind. Each pair must work as a team against the other pair. Aside from this, nothing else has changed except the fact that there are now four paddles.
Pong Doubles was released in September 1973, selling at an MSRP of $820.
This game is known in France as "Coupe Davis" (translates from French as 'Davis' Cup').
