Paddles first appeared in video arcade games with Atari Inc.'s Pong in 1972, while the first console to use paddles was Magnavox's Odyssey that same year. The Apple II shipped with paddles until 1980. The Atari 2600 used paddles for several of its games, as did early home computers such as the Commodore VIC-20. True (potentiometer-based) paddles are almost never employed any more because they stop reading accurately when the potentiometer contacts get dirty or worn, because turning them too far can break them and because they require more-expensive analog sensing, whereas quadrature encoder-based controllers can be sensed digitally. Any recent game that has paddle-type control uses a quadrature encoder instead, even if the game uses paddles on screen (like Arkanoid).
