Same in Sweden! One of the public radio channels (P2) had some nighttime shows with Commodore 64 programs. I can't remember if it was purely BASIC programs or just loaders using data statements for machine code. Seems really impractical now but back then everyone was using cassette tapes to record music from the radio and the C64 had a cassette deck to load software, so it worked quite well. Except that they, as far as I remember, did not use compression so most programs took ages to broadcast.
