Move over vinyl: the cassette tape is back. According to the British Phonographic Industry, sales of this retro piece of technology last year came close to a two-decade peak. Having been the top-selling format for albums in the UK from 1985 to 1992 and then seemingly disappearing (selling only 4,000 units in 2012), last year saw more than 195,000 cassette tapes shifted.
