Philips's development of the Compact Cassette in 1963 and Sony's development of the Walkman in 1979[1] led to widespread consumer use of magnetic audio tape. In 1990, the Compact Cassette was the dominant format in mass-market recorded music.[2] The development of Dolby noise reduction technology in the 1960s brought audiophile-quality recording to the Compact Cassette, also contributing to its popularity.[citation needed]
