This article provides an overview of the origins and early development of sports video games. The first generation of sports video games were developed by scientists in laboratories for academic purposes. Together with the rise of microcomputers and the widespread adoption of television (TV) sets, commercial video games began to emerge in the early 1970s. Like their laboratory predecessors, most of the first-generation commercial games were sports-themed and primarily designed as a platform for competition between players. In the second half of the 1970s, ball-and-paddle-based games began to be replaced by more sophisticated games adopting the rules and actions of real-life sports. By the late 1970s and early 1980s, intense competition between video game companies gave birth to many innovative titles, with various sports disciplines adapted into games. Most of the sports games created in this period were based on competitive sports including American football, basketball, baseball, soccer, and tennis, as well as recreational sports like bowling, pool, and darts, many of them long popular in Western Europe and North America, some with a huge fan base in Japan. They were clearly produced to cater to the needs of gamers and sports fans in the world’s three major TV, personal computer, video game, and sports markets at the time.
