The CD rivaled the cassette in the height of the cassettes popularity with the introduction of the Walkman, also in the late 1970s. The CD had the characteristics people loved about the cassette: it was portable, simple to use, and allowed users to have more control over their listening experience. In addition to this, the CD had a better, more clear sound and was able to maintain it\u2019s original quality longer than the cassette or record.5<\/a><\/sup> CDs became a major money maker for these corporations, becoming more very popular, but seeing as cassette sales still remained largely successful throughout the 1980s and 90s6<\/a><\/sup>, they ultimately didn\u2019t replace the cassette entirely.<\/p>\n\n\n
