The Queen's Christmas message was met with more excitement than usual this year, as fans of The Crown thought they had heard in it a subtle reference to the hit Netflix series.
The Queen began her address by recalling her first televised Christmas broadcast, in 1957.
"Sixty years ago today, a young woman spoke about the speed of technological change," she said.
"She presented the first television broadcast of its kind. She described the moment as a landmark."
"Six decades on, the presenter has evolved somewhat, as has the technology she described. Back then, who could have imagined that people would one day be watching this on laptops and mobile phones, as some of you are today?"
