Television presenter

[1][2] Often, presenters may double for being famed in other fields, such as an actor, model, comedian, musician, doctor, etc.

Others may be subject-matter experts, such as scientists or politicians, serving as presenters for a programme about their field of expertise (for instance, David Attenborough).

Examples of this latter group include British comedian Michael Palin who now presents programmes about travel (such as Around the World in 80 Days), and American actor Alan Alda, who presented Scientific American Frontiers for over a decade.

[3] Another example would be American stand-up comedian Joe Rogan, who is a commentator and post-fight interviewer in UFC.

The term is commonly used in many countries including Canada, New Zealand, The Netherlands, Liechtenstein, Barbados, Sri Lanka, India, Spain, Denmark, Greece, Australia, Egypt, Andorra, Malta, San Marino, Japan and South Korea.
