particularly during Davison-era stories that frequently would have scenes interrupted by partial credit sequences, or feature the sudden appearance of the "electronic scream" sound effect that usually accompanied cliffhangers). This was the most common format used for PBS broadcasts of the series in the 1980s and 1990s. The shortest of these, representing two-episode serials, ran approximately 45 minutes. The longest "Whovie" release, a compilation of the 10-episode The War Games serial, ran for an uninterrupted four hours, though it was more often shown in two two-hour segments; the 14-episode The Trial of a Time Lord was, however, broadcast as four parts, divided, as with the novelisations of this story, into the serial's four major plot lines. This practice carried into the earliest VHS releases in the U.S. and the UK, particularly the first release of The Brain of Morbius which was considerably truncated. It was roundly disliked by many fans and the practice was dropped by the early 1990s. Success of the program in America was sealed by personal appearances of cast members and production staff at science fiction conventions, and by the national airing on PBS of the 20th anniversary special The Five Doctors two days before the BBC.

In 1986, BBC Enterprises organised the Doctor Who USA Tour, a two-year travelling exhibition of props and memorabilia from the program, showcased in a 48-foot trailer decorated with alien landscapes from the show, police box entrances, and a mock-up of the TARDIS interior. Many tour stops included guest appearances from cast members. The statewide PBS chain New Jersey Network was enthusiastic on the series, scheduling pre-1970 serials as well as being the first to broadcast the new season of the program in 1985. NJN staff member Eric Luskin hosted and produced three documentaries on the series, the latter a "behind the scenes" look at the production of the 25th anniversary story Silver Nemesis.
