Music videos first emerged in the 1920s as promotional films for songs. They gained widespread popularity in the 1980s with the launch of MTV, which gave artists a platform to promote their music visually. Michael Jackson's "Billie Jean" video, with its storyline and special effects, set a new standard. Today, social media platforms like YouTube allow unknown artists to self-promote, while all artists use music videos and the internet to connect with fans and sell their music in an increasingly digital marketplace. Developments in camera and editing technology continue to impact music videos by enabling higher production quality.
