The first computer game was developed in 1947 and was based on World War II radar displays. Pong, created in 1972, was the first commercially successful video game and introduced video games to arcades. In the late 1970s and early 1980s, many home console systems became popular but the video game crash of 1983 caused sales to plummet due to an oversaturation of low-quality games. Early computer games were text-based adventures but graphical computer games emerged in the 1980s with titles like Mystery House. Modern computer games have highly detailed 3D graphics and complex virtual worlds.
