On June 20, 1877, Alexander Graham Bell installed the first commercial telephone service, just a year after his historic invention was patented. Established in Ontario, Canada, the first service was quite complex, though Bell realized its potential. He partnered with such organizations as Western Union to complement their telegraph systems, the telephone was used commercially for continental calls in business and political transactions.
