MTV was made in the 1980's and the first Music Video that was played on the channel was 'Video Killed the Radio Star' by the Buggles(1979).
Some other videos that i have looked at are 'Thiller' by Michael Jackson, 'Single Ladies' by Beyonce, 'November Rain' by Guns N' Roses and 'Vogue' by Madonna.
Still to this day, 'Scream' by Michael Jackson remains the largest budgeted Music Video to this day at $7m at the time which now is the equivalent of $11m.
