High Quality Content by WIKIPEDIA articles! A presenter, or host (sometimes hostess, in feminine form), 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 films, a presenter (but not a host) is a usually well-known executive producer credited with introducing a film or filmmaker to a larger audience. A television presenter is a British term (American: host) for a person who introduces or hosts television programmes. Nowadays it is common for minor celebrities in other fields to take on this role, but there are also a number of people who have made their name solely within the field of presenting, particularly within children's television.
