When was the 'TV' invented?

John Logie Baird (born 13 August 1888 - 14 June 1946) was a Scottish engineer and inventor of the world's first practical, publicly demonstrated televisionsystem which was also the world's first fully electronic colour television tube. Although Baird's electromechanical system was eventually displaced by purely electronic systems (such as those of Philo Farnsworth), his early successes demonstrating working television broadcasts and his colour and cinema television work, means the Scotsman was the first to achieve the idea of moving pictures in another place.

75 years ago (7 September, 1927) twenty-one-year-old Philo T Farnsworth performed the first successful demonstration of an all-electronic television system in his laboratory at 202 Green Street in San Francisco, USA.
