The Atari 5200 had sales that exceeded 1 million units. That's also when they introduced their new console called the Atari 7800. The Atari 5200 was released in 1982, and the company announced that they would discontinue the model during a press conference on May 21 of 1984. The 360 joystick was truly an innovation of the time and big improvement over the 8-way joystick that had been previously released. There were also buttons to start the game, pause it and reset it. You would control the Atari 5200 with an analog joystick in a numeric keypad. The software doesn't work between systems, but the two have a lot in common regardless. The Atari 5200 was modeled after the Atari 8-bit computers, and almost all the internal hardware is exactly the same. One of the major competitors in the video game market of the 80's was the Atari 5200.
