The world’s first transcontinental telephone line was successfully voice tested between New York and San Francisco.
Known as Transatlantic No. 1 or TAT-1, the £120 million system actually consisted of two identical cables to allow transmission in each direction.
The 999 service was launched in London on 30 June 1937, and initially covered a 12 mile radius from Oxford Street.
On the 10th March 1876, Scottish-born inventor Alexander Graham Bell made the first successful telephone call when he contacted his assistant, Thomas Watson.
