Premiering the day after the assassination of John F. Kennedy, the first episode of Doctor Who was repeated with the second episode the following week. Doctor Who has always appeared initially on the BBC's mainstream BBC One channel, where it is regarded as a family show, drawing audiences of many millions of viewers; The programme's popularity has waxed and waned over the decades, with three notable periods of high ratings. The first of these was the " Dalekmania " period (c. 1964–1965), when the popularity of the Daleks regularly brought Doctor Who ratings of between 9 and 14 million, even for stories which did not feature them. The second was the mid to late 1970s, when Tom Baker occasionally drew audiences of over 12 million.

During the ITV network strike of 1979, viewership peaked at 16 million. Figures remained respectable into the 1980s, but fell noticeably after the programme's 23rd series was postponed in 1985 and the show was off the air for 18 months.

Its late 1980s performance of three to five million viewers was seen as poor at the time and was, according to the BBC Board of Control, a leading cause of the programme's 1989 suspension. Some fans considered this disingenuous, since the programme was scheduled against the ITV soap opera Coronation Street, the most popular show at the time. During Tennant's run (the third notable period of high ratings), the show had consistently high viewership, with the Christmas specials regularly attracting over 10 million.

The BBC One broadcast of " Rose ", the first episode of the 2005 revival, drew an average audience of 10.81 million, third highest for BBC One that week and seventh across all channels. The current revival also garners the highest audience Appreciation Index of any drama on television.
