On the 10th March 1876, Scottish-born inventor Alexander Graham Bell made the first successful telephone call when he contacted his assistant, Thomas Watson.
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.
