21. Sony MiniDisc (Early 1990s)

“The success and benefits of CD and analogue compact cassette led to a new need, a need based on satisfaction with CD’s wonderful sound, durability and quick random access, and a need based on the portability, recordability and shock resistance of the analogue cassette. It is a need for MiniDisc” – Sony President Noria Ohga. He was correct, at least until MP3 took off. Many of Sony’s portable MD players were quite superb.
