To celebrate the 175th anniversary, the IET History of Technology TPN delivers presentations on selected landmarks and developments in UK telecommunications from those first steps in 1837 to the present.
2012 marks the 175th anniversary of the granting of the UK patent to Cooke and Wheatstone for the first commercially practical electric telegraph. In the same year (1837) Morse and Vail working in America filed a caveat with the US Patent Office in preparation for patenting their system. These were the first steps in the era of electrical telecommunications. There followed the development of the telephone, radio, sound and television broadcasting, advanced communications networks, satellites, personal mobile communications and today's Internet; developments which have had a profound impact on society and the way we live.
Worthy of note is that 2012 is also the centenary of the opening of Britain's first automatic telephone exchange in Epsom and the 50th anniversary of the launch of TELSTAR, the communications satellite which captured the world's imagination. In addition 75 years ago Alec Reeves was developing his ideas for pulse code modulation (PCM) which he patented the following year. An idea before it's time PCM is today a foundation of the modern digital world.
