A host (sometimes hostess, in feminine form) or presenter is a person or organization responsible for running an event. A museum or university, for example, may be the presenter or host of an exhibit. Likewise, a master of ceremonies (also MC, emcee or host) is a person that hosts or presents a show. In movies, a presenter (but not a host) is a usually well-known executive producer credited with introducing a film or filmmaker to a larger audience.
