The usual problem when stuff disappears from public view after a few
weeks or months is the licencing agreement.
At the moment, according to Wikipedia, about two thirds of all BBC radio
output from day one is on a server farm somewhere. For video, they went
through a period where tape was so expensive that for drama, they
re-used it once the programme had been broadcast and repeated, so those
programmes are lost forever, unless someone kept a copy at home. There
are also some problems with disintegrating film and other media which is
becoming unreadable due to the playback gear not being available.
Industry wide, the short lived use of Betamax for digital audio is now a
problem, as the amount of tape needing to be scanned and converted is
more than the expected life of the tape heads available, and nobody
seems to make them now.
There are, apparently, about sixty miles of shelves in a number of
warehouses containing every single document ever created in the BBC.

many years. Who makes the decision of what stuff to keep and one assumes
they do still have them but just not available to the general public.
