Then in they sold their patents to the American Graphophone Company, which later evolved into the Columbia Phonograph Company. Bell used his proceeds from the sale to endow the Volta Laboratory.

Bell undertook two other noteworthy research projects at the Volta Laboratory. In he began research on using light as a means to transmit sound.

In British scientist Willoughby Smith discovered that the element selenium , a semiconductor , varied its electrical resistance with the intensity of incident light.

He was able to demonstrate that the photophone was technologically feasible , but it did not develop into a commercially viable product.

Nevertheless, it contributed to research into the photovoltaic effect that had practical applications later in the 20th century.

When he began experimenting with electrical signals, the telegraph had been an established means of communication for some 30 years.

Although a highly successful system, the telegraph was basically limited to receiving and sending one message at a time.

Bell's extensive knowledge of the nature of sound enabled him to imagine the possibility of transmitting multiple messages over the same wire at the same time.
