If you’re looking for a legal and inexpensive way to catch up on some classic “Doctor Who”, we’ve got good news for you.

The BBC has recently released four stories from the original run of the show on YouTube.

The stories are:

The Edge of Destruction (William Hartnell)

The Krotons (Patrick Troughton)

Carnival of Monsters (Jon Pertwee)

The Caves of Androzani (Peter Davison)

Interestingly, three of the four stories are from the pen of Robert Holmes, who is widely regarded as the best script-writer in the history of “Doctor Who.” (And yes, that includes the new series….)

“Caves of Androzani” recently came out as the top ranked story of all-time in ‘Doctor Who Magazine’s” poll to grade and rate every “Doctor Who” story ever made.

The episodes are commercial supported and, therefore, not available to viewers in the U.K. But the BBC does have a site that offers U.K. users a selection of classic “Doctor Who” stories for viewing.
