Respuesta :
The correct answer is audiences for popular music shifted from radio to television.
In terms of financial success, radio reached its zenith in 1948. Network radio's dominance in the national media, which peaked in 1945 at 46%, began to decline after 1948, falling to 25% by 1952. Most radio stations stopped participating in networks in the late 1950s and shifted to less expensive programming. As a result, radio changed from being a national to a local advertising medium, and television swiftly displaced radio's prominence in American popular culture.
