Science fiction convention in the context of "Science fiction comics"

A convention (or event), in the sense of a meeting, is a gathering of individuals who meet at an arranged place and time in order to discuss or engage in some common interest. The most common conventions are based upon industry, profession, and fandom. Trade conventions typically focus on a particular industry or industry segment, and feature keynote speakers, vendor displays, and other information and activities of interest to the event organizers and attendees. Professional conventions focus on issues of concern along with advancements related to the profession. Such conventions are generally organized by societies or communities dedicated to promotion of the topic of interest. Fan conventions usually feature displays, shows, and sales based on pop culture and guest celebrities. Science fiction conventions traditionally partake of the nature of both professional conventions and fan conventions, with the balance varying from one to another. Conventions also exist for various hobbies, such as gaming or model railroads.

Conventions are often planned and coordinated, often in exacting detail, by professional meeting and convention planners, either by staff of the convention's hosting company or by outside specialists. Most large cities will have a convention center dedicated to hosting such events. The term MICE (Meetings, Incentives, Conferencing, Exhibitions) is widely used in Asia as a description of the industry. The Convention ("C") is one of the most dynamic elements in the M.I.C.E. segment. The industry is generally regulated under the tourism sector.

The World Science Fiction Convention, branded as Worldcon, is a science fiction convention and the annual convention of the World Science Fiction Society (WSFS). It has been held each year since 1939 (except for the years 1942 to 1945, during World War II). The members of each Worldcon are the members of WSFS, and vote both to select the site of the Worldcon two years later, and to select the winners of the annual Hugo Awards, which are presented at each convention.

Cosplay, a blend word of "costume play", is an activity and performance art in which participants called cosplayers wear costumes and fashion accessories to represent a specific character. Cosplayers often interact to create a subculture, and a broader use of the term "cosplay" applies to any costumed role-playing in venues apart from the stage. Any entity that lends itself to dramatic interpretation may be taken up as a subject. Favorite sources include anime, cartoons, manga, comic books, television series, musical artists, video games, memes, and in some cases, original characters. The term has been adopted as slang, often in politics, to mean someone pretending to play a role or take on a personality disingenuously.

Cosplay grew out of the practice of fan costuming at science fiction conventions, beginning with Morojo's "futuristicostumes" created for the 1st World Science Fiction Convention held in New York City, United States, in 1939. The Japanese term "cosplay" (コスプレ, kosupure) was coined in 1983. A rapid growth in the number of people cosplaying as a hobby since the 1990s has made the phenomenon a significant aspect of popular culture in Japan, as well as in other parts of East Asia and in the Western world. Cosplay events are common features of fan conventions, and today there are many dedicated conventions and competitions, as well as social networks, websites, and other forms of media centered on cosplay activities. Cosplay is very popular among all genders, and it is not unusual to see crossplay, also referred to as gender-bending.
