Where was the audio cassette invented?

Answer 1

The Compact Cassette, as it was branded, was developed by Philips in Holland in the early 1960s. It was launched in 1964 when production of the cassettes was started in Hannover, Germany.

Because licensing of the technology was free, the format was adopted by all the major consumer electronics companies and was the most popular recording format for several decades. Although other compact formats were introduced, such as DAT, DCC and Minidisc, none took enough market share to reduce the dominance of the cassette. It was only the low cost of recordable CDs and MP3 and the surrounding technology that eventually displaced the Compact Cassette as the most popular domestic audio recorder.
