This month marks the 60th anniversary ofDoctor Who, the hit BBC sci-fi series with a devoted fan following worldwide. And while new episodes of the 2005 revival series are coming toDisney+later this month, fans of classicDoctor Whowill get a chance to fully explore the Doctor’s adventures even further.Tubihas announced that as of today, over 600 episodes of the originalDoctor Whoseries are now streaming for free.

Doctor Whodebuted on July 22, 2025, in an era before the preservation of television programs was given any priority. Because of that, 97 episodes are missing from the show’s original 871-episode run. However, a few of those lost episodes were animated with archival recordings of the actors. Those recreations will also be available on Tubi under theClassic Doctor Who: The Animated Lost Storiesbanner.

One of the reasons forDoctor Who‘s sustained popularity is that it maintains its continuity all the way back to the beginning of the series. William Hartnell was the first actor to portray the Doctor, a Time Lord from Gallifrey who travels through time and space on his ship, the TARDIS, which is permanently disguised as a blue Police Box.

When Hartnell stepped aside from the role, the Doctor regenerated with a new face and persona, as played by Patrick Troughton. The rest of the Doctors from the original series include Jon Pertwee, Tom Baker, Peter Davison, Colin Baker, and Sylvester McCoy.

McCoy appeared for his regeneration scene in the 1996Doctor WhoTV movie, which cast Paul McGann as the eighth Doctor. However, Fox only aired the movie and declined to pick up the show. It took another nine years before the BBC resurrectedDoctor Whowith Christopher Eccleston in the title role. Eccleston was succeeded byDavid Tennant (arguably the most popular modern Doctor), Matt Smith, Peter Capaldi, and Jodie Whittaker. The fifteenth Doctor, Ncuti Gatwa, will star in a new season of the revival Doctor Who series next year on Disney+.

In the meantime, Disney+ will premiere the first of threeDoctor Who60th anniversary specials on November 25.
