On 7 March 1876 the U.S. Patent Office granted Alexander Graham Bell patent No.
174,465 for an "apparatus for transmitting vocal or other sounds telegraphically." Three days later, on 10 March, Bell transmitted the first intelligible telephone speech in Boston, reportedly calling to his assistant in another room, "Mr. Watson, come here, I want to see you." Where the telegraph carried coded signals requiring trained operators, the telephone conveyed the human voice directly, making instantaneous distance communication accessible to ordinary people. The invention, which Bell developed amid contemporaneous work by Elisha Gray and others, was rapidly commercialised; the Bell Telephone Company was founded in 1877 and telephone exchanges spread through cities in the United States, Europe, and beyond within a decade. The telephone reshaped business, domestic life, and urban organisation, eventually becoming one of the most ubiquitous technologies in the world and the foundation of vast communications corporations. Its development also stimulated advances in acoustics, electrical engineering, and network design that fed into the later growth of electronics and telecommunications.
