On 14 February 1876, Alexander Graham Bell filed patent number 174461 for the telephone. Within a few hours, Bell's rival Elisha Gray filed a patent for a similar invention. It would be seventeen years and more than 600 law suits later before the Supreme Court of the USA decided in Bell's favour and within a year, the first telephone exchange was created.
In 1877, Bell set up the Bell Telephone Company and began making refinements to his designs, whilst keeping the public updated through a series of demonastrations - interest was such that by 1886, more than 150,000 households in the US had a telephone. The first transcontinental telephone call (from New York to San Francisco) was made in 1915.
