<P> Doctor Who had an early Canadian connection . The series was conceived by Canadian expatriate Sydney Newman while he was the BBC's Head of Drama . The series may have been inspired by a short - lived segment (canceled because parents complained that it was "too frightening" for their children) on the Canadian version of Howdy Doody . The segment featured a character surprisingly similar to the Doctor, a puppet called Mr. X who traveled through time and space in his "Whatsis Box" teaching children about history . Newman oversaw this series while working as head of programming for the CBC . Newman maintained a guiding influence over Doctor Who until he left the BBC in 1967 and was in talks with the BBC in 1986, when the show was foundering, to reformat the show and take the role of executive producer . </P> <P> The series made its North American premiere in January 1965 on CBC with the broadcast of William Hartnell's first 26 episodes, fourteen months following their first airing on the BBC . The CBC did not renew the program and it would not reappear on the network for 40 years . </P> <P> The BBC series was originally sold to television stations in the United States in 1972, with Time - Life Television syndicating selected episodes of Jon Pertwee's time as the Doctor . The series did not do well, despite an interesting write - up some years earlier in TV Guide . Apparently, program directors of the commercial television stations that picked up the Jon Pertwee series did not know that the program was an episodic serial, and so it was constantly being shuffled about in the programming schedules . </P> <P> In 1978, Tom Baker's first four seasons as the Doctor were sold to PBS stations across the United States . This time, though, Time - Life was ready to have the Doctor poised for American consumption, by having stage and screen actor Howard Da Silva read voiceover recaps of the previous episode and teasers for the next one which would inform the viewer as to what was going on . To accommodate the teasers up to three minutes of original material was cut from each episode . PBS program planners took the show at face value, but it soon achieved cult status . A few commercial stations including WOR in New York and KVOS in Bellingham also aired the show for a few years . </P>
