Kids in high schools moved in phases from vinyl to cassette tapes (many of which were purchased with music on them) to CDs to mp3s and they're the largest music-buying demographic. Few people bought pop songs on vinyl once they were available on cassette. But I think you're right from the perspective of a recording engineer, or anybody who used reel-to-reel at home, or someone who bought underground punk records all through the 80s, etc.
