The 2005 revival of the BBC’s Doctor Who ended a 16-year drought for fans, some of whom had been keeping up with the Time Lord’s adventures from his debut in 1963 to his cancelation in 1989. While those more recent seasons have been available via Netflix and Amazon Prime, the “classic” library of The Doctor’s early adventures has been a little harder to locate.

On Tuesday, the BBC announced that they were prepared to change that. Beginning immediately, more than 550 episodes of Doctor Who that aired from 1963 to 1989 will be available on BritBox, a U.S. streaming service that has amassed almost every installment featuring Jon Pertwee, Tom Baker, and the five other Doctors who featured in the series prior to Christopher Eccleston taking over the role in 2005.

It’s a valuable acquisition for BritBox, which curates a range of series from the BBC and ITV networks and offers streaming of all their content for $6.99 per month: BritBox says their catalog spans 26 seasons, and lacks just 20 episodes for which they were unable to secure the rights, plus 90 episodes that are believed to be "lost" due to missing footage. BritBox plans to stream audio-only presentations of some of these lost episodes in the near future.
