The video game crash of 1983 (known in Japan as the Atari shock) was a large-scale recession in the video game industry that occurred from 1983 to 1985 in the United States. The crash was attributed to several factors, including market saturation in the number of video game consoles and available games, many of which were of poor quality. Waning interest in console games in favor of personal computers also played a role. Home video game revenue peaked at around $3.2 billion in 1983 (equivalent to $10.1 billion in 2024), then fell to around $100 million (equivalent to $292.36 million in 2024), a drop of almost 97%. The crash abruptly ended what is retrospectively considered the second generation of console video gaming in North America. To a lesser extent, the arcade video game market also weakened as the golden age of arcade video games came to an end.

Lasting about two years, the crash shook a then-booming video game industry and led to the bankruptcy of several companies producing home computers and video game consoles. Analysts of the time expressed doubts about the long-term viability of video game consoles and software.

The North American video game console industry recovered a few years later, mostly due to the widespread success of Nintendo's Western branding for its Famicom console, the Nintendo Entertainment System (NES), released in October 1985. The NES was designed to avoid the missteps that caused the 1983 crash and the stigma associated with video games at that time.

The Atari VCS (renamed the Atari 2600 in late 1982) was not the first home system with swappable game cartridges, but by 1980 it was the most popular second-generation console by a wide margin. Launched in 1977 just ahead of the collapse of the market for home Pong console clones, the Atari VCS experienced modest sales for its first few years. In 1980, Atari's licensed version of Space Invaders from Taito became the console's killer application; sales of the VCS quadrupled, and the game was the first title to sell more than a million copies. Spurred by the success of the Atari VCS, other consoles were introduced, both from Atari and other companies: Odyssey², Intellivision, ColecoVision, Atari 5200, and Vectrex. Notably, Coleco sold an add-on allowing Atari VCS games to be played on the ColecoVision, as well as bundling the console with a licensed home version of Nintendo's arcade hit Donkey Kong. In 1982, the ColecoVision held roughly 17% of the hardware market, compared to the VCS's 58%. This was the first real threat to Atari's dominance of the home console market.

Each new console had its own library of games produced exclusively by the console maker, while the Atari VCS also had a large selection of titles produced by third-party developers. In 1982, analysts marked trends of saturation, mentioning that the amount of new software coming in would only allow a few big hits, that retailers had devoted too much floor space to systems, and that price drops for home computers could result in an industry shakeup. Atari had a large inventory after significant portions of the 1982 orders were returned.

In addition, the rapid growth of the video game industry led to an increased demand, which the manufacturers over-projected. In 1983, an analyst for Goldman Sachs stated the demand for video games was up 100% from the previous year, but the manufacturing output had increased by 175%, creating a significant surplus. Atari CEO Raymond Kassar recognized in 1982 that the industry's saturation point was imminent. However, Kassar expected this to occur when about half of American households had a video game console. The crash occurred when about 15 million machines had been sold, which soundly under-shot Kassar's estimate. Michael Katz, the president of Atari's electronic division, stated that the console market was too saturated as 30 million consoles were sold by 1982, out of the 35 million households with children between the ages of six and sixteen.

Prior to 1979, there were no third-party developers, with console manufacturers like Atari publishing all the games for their respective platforms. This changed in 1979, when Activision was founded by four former Atari video game programmers who left the company because they felt that Atari's developers should receive the same recognition and accolades (specifically in the form of sales-based royalties and public-facing credits) as the actors, directors, and musicians working for other subsidiaries of Warner Communications (Atari's parent company at the time). Already being quite familiar with the Atari VCS, the four programmers developed their own games and cartridge manufacturing processes. Atari quickly sued to block sales of Activision's products but failed to secure a restraining order, and they ultimately settled the case in 1982. While the settlement stipulated that Activision pay royalties to Atari, this case ultimately legitimized the viability of third-party game developers. Activision's games were as popular as Atari's, with Pitfall! (released in 1982) selling over four million units.

Prior to 1982, Activision was one of only a handful of third parties publishing games for the Atari VCS. By 1982, Activision's success emboldened numerous other competitors to penetrate the market. However, Activision co-founder David Crane observed that several of these companies were supported by venture capitalists attempting to emulate the success of Activision. Without the experience and skill of Activision's team, these inexperienced competitors mostly created games of poor quality, which Crane notably described as "the worst games you can imagine". While Activision's success could be attributed to the team's existing familiarity with the Atari VCS, other publishers had no such advantage.
