A quiz channel (also known as a participation television channel) is a television channel that focuses on phone-in quizzes. The quizzes usually focus on puzzles, such as filling in blanks, identifying subjects, or other forms of word puzzles. The channels make money by encouraging viewers to call a toll phone number for the chance to play.

The first dedicated quiz channel is considered to be Germany's 9Live, which launched on 1 September 2001. The best known example in the United Kingdom is Quiz TV (2004–2006), the first to launch in that country. Two major commercial television networks, ITV and Channel Four Television Corporation, through Ostrich Media launched ITV Play and Quiz Call respectively to capitalize on the phenomenon. There are a large amount of quiz channels, particularly on satellite television, with many clones of each other. They are most common at night, where many smaller channels close down and show the quiz channel content in return for a share of the revenue. Portugal also has a substantial amount of quiz programmes, especially on terrestrial channels (including public RTP), however in the daytime they are disguised as pimba-themed talk shows, with blatant phone-in cutaways and quiz participation.

Due to a number of incidents where the fairness of quiz channels and shows came to the attention of the media and regulators in the UK, a number of broadcasters have switched to other types of participation television, focusing primarily on roulette but also bingo^[1] and other casino games^[2] as well as branching out into other forms of participation television, such as televised sex lines.^[3]
