Esports (also known as electronic sports, e-sports, or eSports) is a form of competition using video games. Most commonly, esports takes the form of organized, multiplayer video game competitions, particularly between professional players, individually or as teams. Although organized online and offline competitions have long been a part of video game culture, these were largely between amateurs until the late 2000s, when participation by professional gamers and spectatorship in these events through live streaming saw a large surge in popularity. By the 2010s, esports was a significant factor in the video game industry, with many game developers actively designing toward a professional esports subculture.
