The first Royal Christmas Message was delivered in 1932, when King George V addressed the British Empire from a temporary radio studio at Sandringham House. His successors continued the tradition.
In 1957, 25 years later, Queen Elizabeth II gave the first televised Queen’s Christmas Message. She also spoke from Sandringham House, but instead of addressing the Empire, she spoke to the Commonwealth of Nations. You can watch it in the video, and note how much has changed since she delivered it. You can also watch this year’s Christmas Message on the Internet and on various other media starting at 3 PM GMT (10 AM EST) on Christmas Day.
If you do watch this broadcast, remember that it is customary to stand during the monarch’s address, even if you’re hearing it at home, alone.
