Telecommunications Of The 20th And 21st Centuries



The invention of the telephone back in 1876 by Alexander Graham Bell was the cornerstone of telecommunications for the 20th and 21st centuries.

AT&T as we now know it, was originally called the Bell Telephone Company, the first ever telephone company and the product of Alexander Graham Bell and Gardner Greene Hubbard (Bell's father-in-law and US Attorney General).

Between 1878 and 1879 the first commercial telephone services were set-up in the United States of America and Great Britain. Specifically they were implemented in Connecticut and New Haven within the USA, and London in England, Great Britain.
