Evolution of Pop Music

  • 1920s

    In the 1920s, Tin Pan Alley’s dominance of the popular music industry was threatened by two technological developments: the advent of electrical recording and the rapid growth of radio.
  • 1930

    The ascendance of Tin Pan Alley coincided with the emergence of jazz in New Orleans. An improvisational form of music that was primarily instrumental, jazz incorporated a variety of styles, including African rhythms, gospel, and blues.
  • 1940

    Although banned from some stations, others embraced the popular new music. In 1951, Freed started a late-night R&B show called The Moondog Rock & Roll House Party and began referring to the music he played as rock and roll (History Of Rock).
