1979
London Weekend Television is blacked out during an episode of Hawaii Five-O due to an industrial dispute. The programme started at 8pm.
Later programmes that failed to air due to the strike:
9pm Heartland.
10pm News.
10.30pm A Question of Sex.
11.15pm - 12.45am Film: Die Monster, Die.
The action is part of an ongoing national pay dispute between technicians and management. Unions rejected an offer of a 9% pay rise and are asking instead for 25%.
Tonight's blackout at LWT was caused by a walkout of members of the Association of Cinematograph and Television Technicians (ACTT).
No other ITV regions are affected by strike action tonight.
