“In the early 1980s, engineers over at the Dutch broadcasting organization Nederlandse Omroep Stichting (NOS) had this fantastic idea of distributing computer programs over the radio. Because programs and data were stored on audio cassettes, it was possible for these data cassettes to be played back on a cassette player, and the resulting audio—which sounds very much like a dial-up modem—was broadcasted over the radio waves. Listeners recorded the audio onto cassettes and loaded the programs into their computers. The radio program named “Hobbyscoop” became wildly popular. They even developed a new format called BASICODE to ensure maximum compatibility between different personal computers that were available at the time.”
