Video game culture or gaming culture is a worldwide new media subculture formed by video game hobbyists. As video games have exponentially increased in sophistication, accessibility and popularity over time, they have had a significant influence on popular culture, particularly among adolescents and young adult males. Video game culture has also evolved with Internet culture and the increasing popularity of mobile games, which has led to an increase in the female demographic that play video games.

An online game is a video game that is either partially or primarily played through the Internet or any other computer network available. Online games are ubiquitous on modern gaming platforms, including PCs, consoles and mobile devices, and span many genres, including first-person shooters, strategy games, and massively multiplayer online role-playing games (MMORPG). In 2019, revenue in the online games segment reached $16.9 billion, with $4.2 billion generated by China and $3.5 billion in the United States. Since the 2010s, a common trend among online games has been to operate them as games as a service, using monetization schemes such as loot boxes and battle passes as purchasable items atop freely-offered games. Unlike purchased retail games, online games have the problem of not being permanently playable, as they require special servers in order to function.
