Early music videos originated in the 1930s-1950s as promotional films for songs from musicals. In the 1960s, rock and roll music rose in popularity alongside the growing availability of television, leading artists to experiment more with promotional films for their songs. Considered one of the first true music videos, Bob Dylan's 1965 "Subterranean Homesick Blues" helped establish the format. MTV's 1981 launch brought music videos to the mainstream, making overnight stars of many artists and signifying the rise of music videos as big business productions. Modern times have seen music videos decline on television but thrive on the internet, with lower production costs and viral hits on platforms like YouTube.
