November 2 marks the anniversary of the world's first regular public high-definition television broadcast, which was launched by the BBC from the studios at Alexandra Palace on November 2, 1936.
At exactly 3:00 PM on that day, announcer Leslie Mitchell made history by declaring, "This is direct television from the studios at Alexandra Palace," introducing a brand-new medium to the world.
Today, November 2, 2026, marks the exact 90th anniversary of this momentous event in broadcasting history.
When the service launched on November 2, 1936, the BBC was actually running a live six-month trial between two competing television technologies:
• The Baird System: An electro-mechanical system utilizing 240 lines of resolution, developed by television pioneer John Logie Baird.
• The Marconi-EMI System: A fully electronic system utilizing 405 lines of resolution.
The two companies flipped a coin to decide who would broadcast first on opening day. John Logie Baird's company won the toss, meaning his 240-line system officially inaugurated the service that afternoon, followed closely by the Marconi-EMI system. By early 1937, the Marconi-EMI electronic system was officially chosen as the superior standard.
To commemorate this historic 90-year milestone, Alexandra Palace is hosting a special autumn heritage season titled "BBC TV 90 at Ally Pally".
• Tonight (November 2, 2026), a formal ceremony will take place in the East Court to unveil a World Origin Site plaque, permanently cementing the palace's legacy as the true birthplace of public television.
• The palace's iconic Victorian transmitter mast is being illuminated throughout the season to celebrate the pioneers, engineers, and performers who shaped modern small-screen culture
