few commercial stations including WOR-TV in New York City and KVOS-TV in Bellingham, Washington also aired the show for a few years. Return to Canada: TVOntario and CPN In Canada, TVOntario aired the program starting in 1976 with The Three Doctors and continued with the rest of the original series on a weekly basis until 1990 with series airing two to three years behind the BBC. TVO was also available to many viewers in the United States living in states bordering the Great Lakes. In order to fulfill the network's originally strict mandate as an educational broadcaster, TVO's transmissions of the Third Doctor's stories were hosted by Dr. Jim Dator, a futurist teaching to the University of Toronto, while the first three seasons of Fourth Doctor stories were hosted by science fiction writer Judith Merril, who called herself the "UnDoctor". Both hosts would fill out the show's half-hour time slot through introductions and longer extros which would analyze and discuss the episode critically for several minutes often explaining how a story was at variance with scientific concepts, how it related to science fiction genres, or putting the episodes in a socio-political context. Afterward, this broadcast requirement was relaxed and the extra time was used for the network's standard short subject programming such as Eureka!. TVO continued to broadcast Doctor Who until it lost the rights to the programme in 1990. Meanwhile, in other parts of Canada, Doctor Who became accessible again in the late 1970s as cable television provided many areas with PBS stations piped in from the US, and thus that network's broadcasts of Doctor Who. There were also some local broadcasts of the series outside Ontario: for example, between November 1978 and February 1979 a Saskatchewan-based pay-cable provider, the Co-operative Programming Network (CPN), aired Doctor Who episodes on its Just for Kids channel. 1980s In the mid-1980s, as more stations began to show the existing 1960s episodes, Lionheart (the program's American distributor in the 1980s) dispensed with the older Time-Life tapes containing the Howard Da Silva narrations. Lionheart also offered stations the choice between the standard 25-minute episodes, or a longer version that some stations termed Whovies. These "omnibus editions", or, "movie versions" as they were also known, edited multi-part serials into a single, feature-length film, by cutting out the opening and closing credits, as well as the recap of the cliffhanger, between episodes. (Some edits were clumsy,
