Tel-musici
The Tel-musici was an early entertainment innovation, which used telephone lines to transmit phonograph recordings to individual households. Subscribers called a central "music room" to request selections, which they listened to at home over specially designed loudspeakers called "magnaphones". The service later incorporated live programs, expanding its operations to more along the lines of a general " telephone newspaper".
A Tel-musici company was incorporated in Delaware in 1908, and the service began operation in Wilmington the next year. However, although there were plans to expand throughout the United States, only this single location ever became operational, until it ceased operations around 1914.
