The Circle, sometimes called The Circle UK, is a British reality television game show and the original version of The Circle franchise. Produced by Studio Lambert and Motion Content Group and airing on Channel 4, the show bills itself as a game based around social media, with the concept that "anyone can be anyone in The Circle". Throughout the show, contestants live in the same apartment building but are never allowed to meet. The show is narrated by Sophie Willan, whilst the first and last episode of the first series were hosted by Maya Jama and Alice Levine (later replaced by Emma Willis from the second series onwards). The show has been compared to Big Brother and Catfish in format, as well as Black Mirror episode "Nosedive" with the concept of having to rate other people.
