At launch, the channel will display the first televised Christmas Broadcast of 1957 as its main video.
The access to this restricted footage has been granted to mark the 50th anniversary this year of the first televised Christmas Broadcast.
You can find a full listing of The Queen's Christmas Broadcasts in this section.
She was producer of The Queen's Christmas Broadcasts in 1997, 1998, 2001 and 2002.
Though the Christmas Broadcast was already popular by this time, it had still not yet become the regular tradition it is today.
No Christmas Broadcast took place in 1969 because a repeat of the documentary Royal Family was already scheduled for the holiday period.
With technological advances meaning that viewers have a choice of format - television, radio or internet, the Christmas Broadcast is more accessible than ever.
In this way, the Christmas Broadcast helps to reinforce The Queen's role as a focus for national unity.
The Queen's 1957 Christmas Broadcast was an historic event, as it was the first to be televised.
In 2006 it performed as part of the Queen's Christmas Broadcast, which was recorded at the cathedral.
