Peep Show is Channel 4's longest-running sitcom. The edgy, taboo humor of Peep Show pushes boundaries and fits well with Channel 4's young, risk-taking brand identity. Though the show doesn't attract especially high viewership, around 1.2 million on average, its audience is consistent. Peep Show airs on Sunday nights at 10pm, placing it in a post-watershed timeslot where more risqué content is allowed. Channel 4 has used Peep Show to zone, or place, new comedies after it in hopes of them inheriting Peep Show's young adult fanbase, though this strategy has not always proven successful.
