manually but later, many introduced score counters on the display to assist players in score tracking. Audio capabilities were slow to improve over the generation, starting with the Odyssey, which had no audio, and later moving on to consoles which had buzzers that could produce a small range of beeps and buzzes. Market saturation and the end of the generation In 1976, General Instruments produced a series of affordable integrated chips that allowed companies to simplify console production and lower costs. Due to this, many companies had entered the home console market by the late 1970s. A significant number released consoles that were essentially clones of Atari's Home Pong and many were poorly made and rushed to market, causing the home console market to saturate. The demand for the chip was so high that General Instruments could not supply enough to satisfy all the orders it was receiving causing problems for some smaller companies. Coleco received their order early on allowing them to build up strong production capabilities and have success with their Telstar range. The start of the second generation and the next major advancement in home console technology began in 1976 with the release of the Fairchild Channel F. The technology behind the first generation quickly became obsolete as consumers had the ability to purchase new games for second generation consoles instead of having to purchase new systems when they wanted new content as with the dedicated consoles of the first generation. In comparison to the limited game library for each dedicated console, the Atari VCS launched with Combat, a cartridge containing 27 games. As people transitioned to the newer systems, some companies were left with surplus stock and were selling at a loss. The combination of market saturation and the start of the second generation caused many companies to leave the market completely. These events became known as the video game crash of 1977, as sales of second generation consoles were only modest for the next few years until the arrival of the killer app, the home port of Space Invaders for the Atari VCS in 1980. Home systems There were hundreds of home video game consoles known to have existed in the first generation of video games. This section lists the most notable. Odyssey series In 1972 Magnavox released the world's first home video game console, the Magnavox Odyssey. It came packaged with board game paraphernalia
