“To match up the film with sound, a company called Vitaphone introduced a system that used a standard 3600 RPM motor to rotate a soundtrack disc. To make the audio last the same 11 minutes, the math dictated that the motor be geared down to 108:1. That gives us a rotational speed of 33.33 RPM”

Well I never!
