How many people listened to audiobooks on cassette tape? On a Walkman? (Or anything non-music.) - Lemmy.ca

Shel Silverstein’s Where The Sidewalk Ends read by the author. Peter and the Wolf with orchestral accompaniment.

My mom had a tape that guided you through isometric exercises to do in the car. There was a large tape book always around my house of like 12 cassettes that somehow taught you how to speed read, but I don’t think anyone ever used it.
