Crimewatch (formerly Crimewatch UK) is a long-running and high-profile British television programme produced by the BBC, that reconstructs major unsolved crimes in order to gain information from the public which may assist in solving the case. The programme was originally broadcast once a month on BBC One, although in more recent years it has more usually been broadcast roughly once every two months. It was announced on 15 October 2008 that the BBC would move the production of shows such as Crimewatch to studios in Cardiff.
