Philips introduced the first combination portable radio and cassette recorder, which was marketed as the "radiorecorder", and is now better known as the boom box. Later, the cassette was used in telephone answering machines, including a special form of cassette where the tape was wound on an endless loop. The C-cassette was used as the first mass storage device for early personal computers in the 1970s and 1980s.
In 1972 Philips launched the world's first home video cassette recorder, in the UK, the N1500. Its relatively bulky video cassettes could record 30 minutes or 45 minutes. Later one-hour tapes were also offered.
