A TV format is the overall concept and branding of a copyrighted television program. The most common type of formats are those in the television genres of game shows and reality shows, many of which are remade in multiple markets with local contestants. Recent examples include Survivor, Who Wants to Be a Millionaire?, Pop Idol and Big Brother that have all proved successful worldwide.
Particular models in the genre of sitcoms are often sold as formats, enabling broadcasters to adapt them to the perceived tastes of their own audience. An example is The Office, a BBC sitcom which got adapted as The Office US, Le Bureau in France, Stromberg in Germany, La Job in Quebec and La Ofis in Chile.
A format is licensed by TV networks, so that they may produce a version of the show tailored to their nationality and audience. Formats are a major part of the international television market. Format purchasing is popular with broadcasters, due principally to the lower risk associated with an already-proven idea and the preference of audiences to watch programming tailored to their locality.
Leading companies that handle the creation and sales of programming formats include ITV Studios, Talpa, Endemol and FremantleMedia.
