Fan convention

A fan convention (abbreviated con) is an event in which fans of a particular topic gather to participate in discussions and activities related to their shared interests. Fan conventions are typically organized around specific fandoms, genres, or media franchises, with distinct conventions dedicated to them. The concept of a fan convention has existed since at least 1942 and has evolved into an important part of modern popular culture.

Conventions can be grassroots events organized by volunteer fan communities on a nonprofit basis, commercial enterprises that generate profit through ticket sales and celebrity appearances, or both. Science fiction conventions, which emerged in the late 1930s, established the template that spawned numerous specialized convention types, including those dedicated to anime and manga, tabletop and video gaming, comics, and various subcultures like the furry fandom and the My Little Pony fandom (also known as the brony fandom).

The phenomenon experienced modest growth through the mid-20th century before expanding rapidly during the 1970s, when many of today's major events were established.
