    A History of Video Game Consoles Introduction the First Generation

    A History of Video Game Consoles By Terry Amick – Gerald Long – James Schell – Gregory Shehan Introduction Today video games are a multibillion dollar industry. They are in practically all American households. They are a major driving force in electronic innovation and development. Though, you would hardly guess this from their modest beginning. The first video games were played on mainframe computers in the 1950s through the 1960s (Winter, n.d.). Arcade games would be the first glimpse for the general public of video games. Magnavox would produce the first home video game console featuring the popular arcade game Pong for the 1972 Christmas Season, released as Tele-Games Pong (Ellis, n.d.). The First Generation Magnavox Odyssey Rushed into production the original game did not even have a microprocessor. Games were selected by using toggle switches. At first sales were poor because people mistakenly believed you needed a Magnavox TV to play the game (GameSpy, n.d., para. 11). By 1975 annual sales had reached 300,000 units (Gamester81, 2012). Other manufacturers copied Pong and began producing their own game consoles, which promptly got them sued for copyright infringement (Barton, & Loguidice, n.d.). The Second Generation Atari 2600 Atari released the 2600 in 1977. Although not the first, the Atari 2600 popularized the use of a microprocessor and game cartridges in video game consoles. The original device had an 8-bit 1.19MHz 6507 microprocessor (“The Atari”, n.d.), two joy sticks, a paddle controller, and two game cartridges. Combat and Pac Man were included with the console. In 2007 the Atari 2600 was inducted into the National Toy Hall of Fame (“National Toy”, n.d.).

  • Or, a Prehistory of Interactive Television1

    Or, a Prehistory of Interactive Television1

    The society of the Spectacle is dead: Long live the society of the Carnival; or, a Prehistory of Interactive Television1 by Alison McMahan, Ph.D. ABSTRACT Daniel Dayan’s and Elihu Katz’s theory of spectacle, ceremony and festival levels of engagement is here applied to the various types of interactive television, from choice and time-shift types, to hyperserials (as defined by Janet Murray in Hamlet on the Holodeck) to the kind of interactive television where viewer/players can alter the content. The closest we have right now to this festival-approach to interactive television are graphic online MUDs such as Ultima Online and massive multiplayer games. Console boxes, the first of which was the Sega Dreamcast, offer a festival model of interactive televisual engagement along with a low-cost convergence of television, internet and computer. If we accept that multiplayer console games are a model for the interactive television of the future, we can then start defining an aesthetics of interactive television based on computer games. KEY WORDS Interactive television, computer games, videogames, console boxes, hyperserial, spectacle, ceremony, festival. The idea I wish to explore in this paper is that Game Consoles, among which the Sega Dreamcast was the first to include Internet access and on-line games, are the first true form of interactive television. If we accept this hypothesis then we can look at a variety of other phenomena, from web casting to reality TV to computer games, as precursors to interactive television that have been remediated in the form of interactive television we have now.

"During its first year, people found the Famicom to be unreliable, with programming errors and freezing rampant. Yamauchi recalled all sold Famicom systems, and put the Famicom out of production until the errors were fixed. The Famicom was re-released with a new motherboard." Original NES (Nintendo Entertainment System) (1985) (US, Europe, Australia) Same as Famicom, but with slightly different pin-outs on cartridge slot, and controllers/expansion ports: Front-loading 72-pin cartridge slot, without external sound-input on cartridge slot, without microphone on joypads, with lockout chip.
