I remember the Monkees. I was about 11. During one of the songs, my brother, who is now 45, was about 5-6 months old and was bobbing his head to the music.
A lot of people say the Beatles started the video, they played the songs from their movies. Actually during the 40s, they had "Soundies".
He is a clip from the Blockbuster site.
Synopsis Of Soundies: A Musical History
Soundies: A Musical History collects a number of short musical films that played on a film jukebox called Panoram in the 1940s. Many consider these films to be the very first music videos, and this documentary includes appearances by some of the most beloved musical artists of all time including Louis Armstrong. ~ Perry Seibert, Rovi
