SYNOPSIS

Back in 1962, a report on the viability of science fiction as a genre for BBC drama had concluded that it could never guarantee a large TV audience. 'Doctor Who' was inspired by that report and in this document from the BBC Audience Research Department we can finally see whether there was any truth in those early findings. As expected, those who liked the show seem passionate about it, while those who didn't like it appear almost as determined.
