How many years did the British soap opera "Brookside" run for?

"Brookside" is a British soap opera set in Liverpool, England. The series began on the first evening of Channel 4 on 2nd November 1982 and ran for 21 years until 4th November 2003. It was originally intended to be called "Meadowcroft", the series was produced by Lime Pictures (then Mersey Television), and it was conceived by Phil Redmond.

The show became very successful and was often Channel 4's highest rated programme for a number of years in the mid-1980s, with audiences regularly in excess of nine million viewers. It is notable for realistic and socially challenging storylines. From the mid-1990s, it began raising more controversial subjects under the guidance of new producers such as Mal Young and Paul Marquess. It is especially well known for broadcasting the first pre-watershed lesbian kiss on British television in 1994.

Although the series had a long and successful run, by 2000 its viewing figures were in terminal decline, and low ratings eventually led to its cancellation in June 2003. The final episode was broadcast on 4 November 2003 and was watched by around two million viewers.
