Remember when you had to put the best of your treasured vinyl collection onto cassette just so you could play it in the car? When retail outlets actually sold albums in cassette format to suit people who travelled or moved house a lot and wanted to keep their music collection to a manageable size? When bootleggers recorded to boomboxes and DAT was something that went with DIS?
There's a scuplture at the International Surgical Museum that illustrates the Death of the Cassette Tape. See it here.
