when were cassette tapes invented

Cassette tapes, also known as compact cassettes, were invented by Dutch engineer Lou Ottens and his team at Philips in 1962. They were first introduced to the public at the Berlin Radio Show in 1963 and made their debut in the U.S. market in 1964. Initially designed as a more convenient and portable alternative to reel-to-reel tapes, cassette tapes quickly became popular for audio recording and playback.
