However, in 1906, private inventor Dr. Lee De Forest invented the three-element vacuum tube known as the audion. This device allowed a long distance phone signal to be amplified. The patent was purchased six years after its invention by AT&T in 1912. Once AT&T purchased the patent, they devised a way to increase the vacuum of the audion chamber and lessened the quantity of internal gases, allowing the device to be used even more effectively for international long distance telephony. This invention spurred the progress of coast-to-coast long distance until on June 17, 1914, the last pole went up in Wendover, Utah, linking the lines originating on the West Coast and the East, enabling the first transcontinental telephone call, which was not made until January 25, 1915. This momentous event was delayed so long so that it would coincide with the exposition that was to be held in San Francisco that year celebrating the end of construction on the Panama Canal.
