Murder Prevention was a British police drama inspired by the real-life Homicide Prevention Unit within the Metropolitan Police. It was produced for Five by World Productions who previously produced the television series The Cops. The series consisted of three two-part stories. Later repeats edited the two-parters so that they were screened as three longer running episodes. According to series creator Declan Croghan, "Murder Prevention is the first pre-crime drama ever, anywhere."

Exposure is a current affairs strand, broadcast in the United Kingdom on the ITV network. The programme brings together six films made by different producers exploring and investigating foreign and domestic topics, reporting on issues and telling human stories. The series was commissioned for ITV by Peter Fincham, ITV Director of Television and is a sister show to year-round current affairs strand Tonight. It made its debut on Monday 26 September 2011 - airing at 22.35, directly after ITV News at Ten.
