Coronation Street is a British television soap opera set in Weatherfield, a fictional town in Greater Manchester based on Salford. Created by Tony Warren, Coronation Street was first broadcast on 9 December 1960.
The show has been on the air for over 51 years. Coronation Street is produced by ITV Granada Television and shown in all ITV regions on the ITV Network. It has been filmed in Manchester at the Granada Studios since its inception, but filming will move to a new set at Media City in Trafford in 2013.
Since first being aired, it has been one of the most financially lucrative programmes on British commercial television, underpinning the success of its broadcaster ITV and its franchise Granada Television. On 17 September 2010, it became the world's longest-running TV soap opera in production, after the United States soap opera As the World Turns ended.
