Music on hold was created by Alfred Levy, an inventor, factory owner, and entrepreneur. In 1962, Levy discovered a problem with the phone lines at his factory. A loose wire was touching a metal girder on the building. This made the building a giant receiver so that the audio broadcast signal from a radio station next door would transmit through the loose wire and could be heard when calls were put on hold. Alfred Levy patented his work in 1966 and this accident and patent creation began the evolution for today's music on-hold and the concept of on-hold messages.
