Gogglebox is a British reality television series created by Stephen Lambert, Tania Alexander and Tim Harcourt, and broadcast on Channel 4.

The series documents families and groups of friends around the United Kingdom who are filmed for their observations and reactions to the previous week's television from their own homes.

Lambert is a media executive who had previously launched the Channel 4 television shows Wife Swap, Faking It, Undercover Boss, and The Secret Millionaire.

Alexander was Director of Factual Entertainment at Lambert's independent production company Studio Lambert, who said the idea was for Gogglebox to be a mix of the ITV comedy show Harry Hill's TV Burp, which looked back at the previous week's television, and the BBC sitcom The Royle Family, which centres on a television-fixated family, but with real, ordinary people.

[4] Harcourt, a Creative Director for Studio Lambert, had the original idea for Gogglebox while watching the 2011 London riots,[5][6] and along with Alexander, devised the format for the show.

She was replaced by Studio Lambert's deputy creative director, Mike Cotton, alongside Gogglebox executive producer Leon Campbell.

In later series, members of the show's production team visited random houses and held up a card that contained something, such as a picture of the British Prime Minister or a Daily Mail headline, and noted how quick the person responded and any funny, interesting, or insightful comments they had.

Four-person crews circulate between the households two or three evenings each week, and the cast watch the same programs as each other, which can amount to as much as six hours of television.

Alexander said that the biggest problem encountered during the filming stage is the cast forgetting that they are meant to be commenting and having to be given "gentle prompts".

[4] She added that "the craft happens over the last couple of days before it goes out on the Friday", which usually begins on a Tuesday afternoon or the Wednesday, with the production team working through the night to produce an initial cut.

[10] The team reviews the first edit on a Thursday afternoon, after which further cuts or tweaks are made before the narration is recorded and the episode is delivered for broadcast.

[16] In 2017, a spin-off show titled Vlogglebox aired on E4, which featured reactions from 16 to 24-year-olds as they watch online content on their smartphones, laptops or tablets.

S4C issued a competitive tender for the production rights on the same day, with the show scheduled to debut in autumn 2022 as part of the channel's 40th anniversary.
