It was 80 years ago today, 2nd November 1936, that the first regular scheduled high definition (and in this case high definition is considered a minimum of 240 lines) was launched by the BBC. Previously there had been a regular low definition (30 lines - yes 30 lines - using "mechanical" television) between 1929 & 1935.
The two youtube links below from the mid 1970s and early 1980s have been proved by later research to have been not entirely accurate as they are rather dismissive of the content and quality of the earlier low definition service, later research uncovered that this was not necessarily the case from recordings that were made at the time. These were from both 78 rpm discs (a failed experiment) and Dictaphone type (amateur) recordings made rather later on but still have much interesting material about how it all started out.
