29 April 2011 – the royal wedding between Prince William and Kate Middleton earned its own doodle in the header of YouTube. Personally I didn’t watch the wedding online, but obviously – it was the biggest video event from some time now. No Google royal doodle yet, though.
The logo was uploaded at http://s.ytimg.com/yt/img/doodles/royal_wedding-vflZ8V2om.png … and it’s still there.
