Discrimination against african americans and segregation
<span>the rise in the popularity of music videos affected the radio industry in a positive and negative way... Wider ranges of music became memorable for more than just the sound, and easily accessible, the next best thing to being there live to see your favorite artists... This broadened the types of music radio stations played, with it came a double-edged sword in the form of dedicated music television channels, which went on to multiply many times until tv has become saturated by clones... Radio must try harder than ever to remain engaging, going beyond just playing music.</span>
