The document compares the scheduling of two television programmes on different channels. Citizen Khan airs on BBC1 on Fridays at 9:00pm, after the watershed. It is scheduled in prime time and uses strategies like inheritance, hammocking and zoning to attract and retain a mass audience. The Big Bang Theory airs on E4 daily in a stripped schedule at prime time. It uses zoning and pairing to target E4's niche audience with imported entertainment programming.
