In the early 1960's, The Philips Company of the Netherlands, invented the cassette tape. These cassettes were first used to record dictations, however that all changed in the 1970’s when many people began to use cassettes to record music.

CD’s could hold a little more than cassette tapes. The most popular cassette tapes could play up to 46 to 60 minutes of audio; however, the new CD’s could hold up to 74 to 80 minutes of audio.
