In the late 1970s, a popping group called Electric Boogaloos (earlier known as the Electronic Boogaloo Lockers) from California greatly contributed to the spread of popping, partly because of their appearance on the television program Soul Train. The Electric Boogaloos themselves state that around the years 1975-1976 their founder Sam Solomon (a.k.a. Boogaloo Sam) created a set of movements that evolved into the styles known today as popping and boogaloo after being inspired by one of the pioneer locking groups known as The Lockers as well as a fad dance popular in the 1960s known as the jerk.

Many confirm the Electric Boogaloos' story that Boogaloo Sam came up with the basics of popping. READ MORE
