There was a show on the radio about BASIC programming, with programming samples. You'd have to record the show on a cassette tape, because the code was transmitted as audio output. You could do the excersise, and then check your code by playing the tape on your Commodore 64. I still think that was a pretty ingenious thing, sending code over the radio!
Ah, and the BBS'es of the early'90's... So much time wasted there!
