Odyssey 500
With the same trio of games as the Odyssey 400 – Tennis, Hockey/Soccer and Smash – the Odyssey 500, released in 1976 by Magnavox, would appear 
to not be much of an upgrade, but in fact, it’s an absolutely critical turning point for home video games: the Odyssey 500 did away with squares and rectangles to represent the player, and introduced character sprites – hardware-generated characters that roughly mimicked the shape of a human being.

The Game: Activated by leaving a cartridge out of the slot, powering the system up and pressing one of the selector keys, Tennis and Hockey are built into the system. Timed games can be selected, and the traditional rules of each sport apply. (Fairchild, 1976)
After the baffling backward step of the Odyssey 400, Magnavox’s Odyssey 2000 saw a return to the Pong-inspired, single-paddle control scheme, with digital scoring restored as well – Magnavox had decided to rest the Brown Box design (and the subsequent variations on it) permanently in favor of, once again, the General Instruments AY-3-8500 “Pong on a chip” processor. Packaged in a red casing, this would be the last anyone would see of the smoothly rounded-off, integrated Odyssey console. The next system to bear the name would return to its roots – with wired controllers that weren’t necessarily stuck to the main console – and look forward, with a futuristic new design that stands up even today. 
It adds nothing to the Odyssey 2000’s “four action-packed video games,” but the Odyssey 3000 is a quantum leap in the design aesthetic of the console itself. Finally breaking away from the basic casing design that had been in place since the Odyssey 100, Odyssey 3000 packs four games (well, really just three plus a Tennis “practice mode”) into a sleek, futuristic-looking black wedge with highlights that almost anticipate – believe it or not – the look of the computer screens in Star Trek: The Next Generation (though to be more realistic, it may have been influenced by the design line of Atari’s Fuji logo). The controllers are detachable but hardwired, and nestle snugly into the console itself.
