My first post here - a lurker with an interest in old electronics - but electronic TV broadcasting got underway in November 1936 in London England (not commercial but electronic TV broadcasting is 75 years old this year and Schoenburgs(sic?) EMI team (Blumlien invented the video waveform as we know it) did an amazing job at the time with the 445 line system that lasted until the mid-1980's). Farnsworth's image disector tube was not really practical - due to the lack of a photo-multiplier - although it found industrial uses later and the EMI team used a derivative of the RCA's Iconoscope called the EMItron. TV had many fathers (can't remember the Hungarian dude who came up with interlacing but EMI used that) which probably explains why it is such a mongrel! I will return to lurking after that dump, please correct any misconceptions I might have!
