LONDON -- "Doctor Who" fans, rejoice! The BBC says it has recovered nine episodes of the sci-fi series that once were feared lost.
The broadcaster says the missing episodes plus two others were found in the storeroom of a television relay station in Nigeria.
"Doctor Who," which is celebrating its 50th anniversary this year, was first broadcast in 1963 and remains one of the BBC's most popular programs.
Some early episodes were lost because the broadcaster wiped the tapes clean for reuse.
The BBC says the lost episodes were tracked down by tracing records of overseas shipments of BBC tapes for transmission.
The recovered episodes date from 1967 and 1968 and feature Patrick Troughton, the second of a dozen actors to play the show's time-traveling hero, The Doctor.
They will be offered for sale on iTunes and DVD.
