Mark Corrigan has steady employment for most of the series and Jeremy "Jez" Usbourne is an unemployed aspiring musician.Mark is financially secure but is always shy and socially inept with a cynical attitude which makes him the total opposite of Jeremy. Jeremy, on the other hand, usually has a much more positive and vigorous perspective on the world, yet his declared talent as a musician has to be recognised. He is more successful with the opposite sex than Mark but he is not as famous or interesting as he would like to think himself.
Peep Show is considered to be a cult television show. Early reviews called it "promising" and recognised it had "the sniff of a cult favourite". It was claimed that the series in years to come, Peep Show will "be seen as the pinnacle of comedy it obviously is." by Jane Simon of the Mirror. It also won several awards including the titles "The Best Returning British TV Sitcom 2007" and "Comedy of the Year 2008" in The Comedy.co.uk Awards. The Guardian newspaper described it as "the best comedy of the decade" while The Times praised the show's "scorching writing" and named it the 15th best TV show of the 2000s.
Channel 4 announced in September 2013 that the show will end with its ninth series, which will air in 2014.
