The comedy, which launched in 1968 and ran for nine series and 80 episodes, drew in audiences of more than 18 million at its peak and made actors like Arthur Lowe and John Le Mesurier into household names.
BBC2 airs Saturday night re-runs of the show while Gold broadcasts repeats on weekdays, and now the two channels are celebrating the anniversary with a special raft of programmes.
