Music videos have a long history dating back to early promotional films that were sometimes set to music. Early forms included Soundies, short musical films from the 1940s that played in visual jukeboxes. The first TV short music clips were the Snader Telescriptions from 1950-1954. Music videos began being produced for music programs in the 1960s and 1970s to promote artists like the Beatles. MTV launched in 1981 and became the dominant channel for music videos, reaching over 320 million homes worldwide. Michael Jackson's "Thriller" video in 1983 set new standards for production and was one of the most iconic and successful music videos ever made.
