The document compares music videos from the 1970s, 1990s, and 2010. It summarizes the key differences between each decade's music video styles and technologies. In the 1970s, videos used basic graphic effects and green screens. Videos in the 1990s focused more on the artist and suggestive dancing. By 2010, video quality improved significantly, and videos included storylines to engage audiences rather than just focusing on effects or sexuality.
