Music videos today follow many of the same conventions established by the first music video "Video Killed the Radio Star". Common conventions include alternating between shots of the artist performing and scenes advancing a narrative. Camera movements and close-ups are used to emphasize the artist. Modern music videos primarily function as marketing to promote the artist and their music. They aim to intensify the song's lyrics and music through complementary or contrasting visuals. Technology has advanced video production quality and special effects to make videos more innovative and memorable.
