London Weekend Television (LWT) was the ITV network franchise holder for Greater London and the Home Counties at weekends, broadcasting from Fridays at 5.15 pm (at 7 pm until 1982) to Monday mornings at 6am. From 1968 until 1992, when LWT's weekday counterpart 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 counterpart was Carlton Television, the transfer occurred invisibly during a commercial break as Carlton and LWT shared studio and transmission facilities.
