Happy Birthday to BBC television! The BBC began the world's first high definition regular television broadcasts from Allt Pally (Alexandria Palace) in north London 75 years ago!
"The official opening ceremony was on 2 November 1936.
After the toss of a coin, the pilot programme was transmitted first on the Baird system and then after a brief pause, the entire programme was done again live on the Marconi-EMI system.
So the BBC's second television programme was also its first repeat."
