In 1975, Atari partnered with Sears, Roebuck and Co. to produce and distribute a home video game version of the smash arcade hit Pong. Marketed under both the Atari and Sears Tele-Games brands, the home console version of Atari's Pong was phenomenally successful. Pong sparked the home video game revolution and spawned numerous imitation consoles, produced by companies including Radio Shack, Coleco, and Unisonic. Yet another company to produce a ping-pong style home console was APF Electronics, Inc. APF's initial Pong clone was the APF TV Fun, released in 1976, and the following year they produced the APF TV Fun Sportsarama. The Sportsarama model was loaded with eight games, several of which were shooting games designed to be played with the system's light pistol (an accessory not included with the majority of contemporary Pong-style games, including Atari's version). This artifact, the APF M-1000, was released in 1978. It came pre-loaded with the game Rocket Patrol, and allowed for the use of interchangeable cartridges, though only 10 were produced. Unfortunately, APF was unable to duplicate Atari's success, and production of the APF TV Fun line of consoles was short-lived.
