Many thanks to Mike Barraclough who shares this news:

“BBC has today launched a website publishing every BBC programme ever broadcast by the Corporation from digitised editions of the Radio Times 1923-2009. Getting occasional internal errors at the moment presumably due to heavy use following publicity. Well designed and easy to search. http://genome.ch.bbc.co.uk/“

The archive is quite deep–if you’re the nostalgic type, expect to spend a few hours browsing.
