Viewers encountered blank television screens on the morning of 10 August 1979, and were left without any programmes, such as soap opera "Coronation Street" as well as various sporting events. Only two ITV companies broadcast anything other than a specially-made apology caption during this time, those being Channel Television, who broadcast a time-restricted service of local programming, films and imported television series (on film, as Channel had no videotape facilities at the time) and in the Yorkshire Television region, who interrupted their strike card to broadcast appeals on behalf of the West Yorkshire Police in their hunt for the Yorkshire Ripper.
