The Royal Channel

Queen Elizabeth delivered her address on both television and on YouTube this year. In fact, the Monarchy has set up The Royal Channel, which, according to the header, is "The Official Channel of the British Monarchy." I don't think the specific address is a huge deal, as she still used TV, however, the fact they set it up on YouTube, rather than using their own site, only goes to show the power of the site (it's also linked off the British Monarchy homepage).
