The document discusses how R&B music videos have changed over the decades from the 1980s to present day. In the 1980s, videos featured formal costumes, dance routines, and close-ups with narrative stories. By the 1990s, costumes became more casual as the music focused more on emotion with slower, intimate videos. Modern R&B videos are more promiscuous and focus on sexuality, money, and material goods within narrative plots, unlike the formal and emotive styles of earlier decades.
