The Queen has launched the new British Monarchy web site, developed with the help of World Wide Web inventor Tim Berners-Lee.
The new site, the third version since it was first launched in 1997, features a host of new sections and technologies.
For instance, Google maps is integrated with the Royal Diary of Engagements, while the Royal Channel is integrated with YouTube. The site promises to make greater use of video and has a new Content Management System (CMS) making it easier to update.
The Royal website also features a wealth of new content, including expanded information on the Commonwealth Realms and a new section on royal animals.
The British Monarchy Website is visited by about 250 000 users from around the world each week.
The new site features audio and video footage supplied by the BBC and the British Film Institute. These include the then Princess Elizabeth's 21st birthday broadcast, which was made in Cape Town in 1947.
It also includes documents from the archives.
