London Weekend Television (
LWT) was the
ITV network franchise holder for
Greater London and the
Home Counties at weekends, broadcasting from Fridays at 5.15pm (prior to 1982 at 7pm) to Monday mornings at 6am. From 1968 until 1992, when LWT's weekday neighbour was
Thames Television, there was an on-screen handover to and from LWT at each end of the weekend; from 1993 to 2002, when LWT's weekday neighbour was
Carlton Television, the transfer occurred invisibly during a commercial break as Carlton and LWT shared studio and transmission space.
