Information: - Reality television is a genre of television programming that documents supposedly unscripted real-life situations, and often features an otherwise unknown cast of individuals who are typically not professional actors, although in some shows celebrities may participate. It differs from documentary television in that the focus tends to be on drama, personal conflict, and entertainment rather than educating viewers. The genre has various standard tropes, including "confessionals" (also called "talking heads" or "interview segments") used by cast members to express their thoughts, which often double as the shows' narration. In competition-based reality shows, a notable subset, there are other common elements such as one participant being eliminated per episode, a panel of judges, and the concept of "immunity from elimination." - The Sky 's the Limit was a United Kingdom game show first broadcast on 10 July 1970 , being a travel - themed version of Double Your Money .

Alternatively, a "gameshow" can be a demonstrative program about a game (while usually retaining the spirit of an awards ceremony). In the former, contestants may be invited from a pool of public applicants. On some shows, contestants compete against other players or another team, while other shows involve contestants playing alone for a reward or a high score. Game shows often reward players with prizes such as cash, trips and goods and services provided by the show's sponsor prize suppliers, who in turn usually do so for the purposes of product placement. One of the reasons that television broadcasters make game shows is because they are substantially less costly than producing scripted drama shows. Some TV game shows fall under the category of reality television. - Associated-Rediffusion, later Rediffusion, London, was the British ITV contractor for London and parts of the surrounding counties, on weekdays between 1954 and 29 July 1968.
