This Day in Information: 1st Telephone Switchboard

Posted on January 28, 2011 by GilPress

Two switchboards were used on Islesboro, Maine from ca. 1915 to 1962

Today in 1878, the first commercial switchboard began operating in New Haven, Connecticut. It served 21 telephones on 8 lines consequently with many people on a party line. On February 17, Western Union opened the first large city exchange in San Francisco. The public switched telephone network was born.
