The BBC has made available its entire archive of "Desert Island Discs", spanning some 60 years. (Very nicely done site, but would it have killed them to include a Grooveshark playlist for each castaway? It's the web, make it work!)
As a concept, Desert Island Discs is so early-20th century. Now, one could simply ask for a Wifi connection (as a luxury item) and just ruin the fun.
