I assume you know this, but just for clarity:
The Royal Family Channel - run by ITN
https://www.youtube.com/user/royalweddingchannel
The Royal Family -the official channel of the British Monarchy
https://www.youtube.com/user/TheRoyalChannel
I do yes but clarity is always good.
As an aside it is silly to have two channels with such similar names. ITN should call it the ITN royal family channel to avoid confusion.
