The Philips Company of the Netherlands invented and released the first compact audio-cassette in 1962. They used high-quality polyester 1/8-inch tape produced by BASF. Recording and playback was at a speed of 1.7/8 inches per second.

The next year in the U.S. sales began of the Norelco Carry-Corder dictation machine that used the new cassette tape. The consumer's demand for blank tape used for personal music-recording was unanticipated by Philips.

I believe the first "portable" radio was a 1924 Zenith and the 8 track was invented by "madman Muntz" in the 1960's.
