In 1923, Harrison of the Western Electric Company filed a patent for a phonograph in which the mechanical design was entirely represented as an electrical circuit.

During the first part of the 20th century, Pathé became the largest film equipment and production company in the world, as well as a major producer of phonograph records.

By 1924 such dramatic progress had been made that Western Electric arranged a demonstration for the two leading record companies, the Victor Talking Machine Company and the Columbia Phonograph Company.

He wrote a list of what the phonograph might be good for when he invented it, and kind of only one of his ideas turned out to have been the right early idea.

The driving force behind the film operation was Charles Pathé, who had helped open a gramophone shop in 1894 and then established a phonograph factory at Chatou on the western outskirts of Paris.

I was out of the air force in 1956. No, no, that's not true I went in in 1956, came out in 1959, was working at the University of Washington, and I came up with an idea, from reading a magazine article, for a new kind of a phonograph tone arm.
