It's incredible that the BBC couldn't see the value in spending 10 pounds, or so, to archive every episode. They must have been smoking some bad shit back then.

They just never thought the show would be popular enough to warrant saving the episodes. Doctor Who may be the most notorious show hit. But it was common practice and most of the 60's shows were erased due to this practice.
