Radioarchive.cc was a huge loss. It was a torrent archive of BBC radio programs, mostly dramas and panel shows. Since it died, there have been few places to get BBC radio dramas, many of which are broadcast once, are available for listening on streaming free for a month (worldwide), then are unavailable in perpetuity. Many of them also have well-known authors or are adaptations of well-known novels or even films and many also have notable actors in their casts.
This does not make up for the death of Radioarchive.cc, but it is the next best thing.
For those of you who need an introduction to the amazing world of BBC radio dramas, may I present two for your listening pleasure:
A familiar drama with a familiar cast- https://archive.org/details/GoodOmensBBCr4
An epic with a star (Ian Holm) who later ended up in the movie adaptation- https://archive.org/details/tolkien-lord-of-the-rings-bbc
Internet archive should allow for people to put up donations to cover the cost of whatever obscure website they want preserved. Assign a priority incase funds get low.
