The document explores how the genre of R&B music has changed over time through its music videos from the 1980s to present day. It notes that in the 1980s, videos featured large dance routines and formal costumes, while in the 1990s, videos became more emotive and narrative-based with casual clothing and close-up shots as the music evolved. Modern R&B videos are described as more promiscuous and focusing on narratives of vulgarity, sexuality, money and materialism compared to previous decades.
