The invention of the telephone
Invented in 1876 by Alexander Graham Bell, the telephone has revolutionized the daily lives of almost every American. The internet, cell phones, pagers, pda's, laptops, and other communications devices all originated from this simple and often taken for granted device. From the early 1880's to modern times the telephone has drastically evolved. From just a simple device which converts sound to electrical impulses, to a sleek thin cell phone capable of doing almost everything imaginably possible on a device only the size of your hand. In 1876 while trying to improve on the already existing telegraph, Alexander Graham Bell and his assistant Watson accidentally transmitted a gentle twang of a clock spring into the next room where Bell heard the sound. "Snap that reed again, Watson" cried Bell. This was the first time in the world that a complete sound was carried along wire and transmitted perfectly for another person to hear.
The first automatic telephone exchange which didn't involve a switch board was patented and installed by Almon Strowger in 1891. The first rotary Telephone was developed in 1923 by Antoine Barney. And since the invention of the phone, cell phone, and internet the technology of them has been constantly changing for the better. In 1979, the first commercial cellular phone system began operation in Tokyo. A year later, public trials of the new cellular phone system were started in Chicago, IL with over 2000 trial cellular phone customers. Although in police cars already the mobile phone as we know was not introduced to the public for another four decades. The first pager, as we are familiar with them today, was Motorola's Pageboy I, introduced in 1974. In the 1880s Long distance service was established and grew using metallic circuits. 1879 Telephone subscribers began to be designated by numbers rather than names. In 1900 The first coin telephone was installed in Hartford, Connecticut. 1888 The common battery system, developed by Hammond V. With only 22 subscribers to the phone service the average charge was only $1. By 1977, AT&T Bell Labs constructed and operated a prototype cellular phone system.
