One of the first demonstrations of TV transmission, albeit using a mechanical instead of an electronic system, occurred 90 years ago in 1926, but Philo Farnsworth demonstrated the first electronic television – the true ancestor of today's TV sets – on Sept. 3, 1928.
"It was a great day, a memorable day, a day for the history books. It was a day when people - gasp! - watched TV. Not your idea of a great day, perhaps. But for the 50 people who witnessed what has gone down in history as the 'first' demonstration of television - 90 years ago today, Jan. 26."
