What is "duopoly"

n. 1 (context economics English) A market situation in which two companies exclusively provide a particular product or service. 2 (rfdef: English)

A true duopoly (from Greek duo δύο (two) + polein πωλεῖν (to sell)) is a specific type of oligopoly where only two producers exist in one market. In reality, this definition is generally used where only two firms have dominant control over a market. In the field of industrial organization, it is the most commonly studied form of oligopoly due to its simplicity.

A duopoly (or twinstick, referring to "stick" as jargon for a radio tower) is a situation in television and radio broadcasting in which two or more stations in the same city or community share common ownership.

Duopoly (entertainment company) is an independent film, television and multi-platform content company founded in 2002 by Catherine Tait and Liz Manne. Tait and Manne, both veterans of the independent film and television industries, established the company in order to develop and produce compelling new content properties, to forge productive relationships with talent and creators from Canada and the US, and to help create new businesses in the entertainment space. Among Duopoly's productions are Pure Pwnage, Chilly Beach, Bam Bam and Celeste starring Margaret Cho, and Yam Roll.
