The royal wedding of Prince William and Kate Middleton will be streamed live on YouTube. Of course.

Obviously Google is excited about it. The comapny is in the midst of turning YouTube into not only the biggest web video destination, but a destination for live events. Earlier this month, they announced YouTube Live – said destination and a platform for streaming live video that will be available for select partners (at least at first).

Of course, the more interesting things people have to watch on YouTube, the better it makes Google TV look too. This past weekend, Coachella, the giant music festival, was streamed live on YouTube.

“Google search trends show that in addition to the UK and the US, the top ten countries searching for ‘royal wedding’ include places like Singapore and the Philippines,” says Google’s Rachel Ball. “In response, we’ve been working to make as much of the big day as possible accessible to everyone. We previously announced the expansion of our Google Earth 3D imagery to offer a ‘Royals’-eye’ view of the entire wedding procession, complete with 3D images of iconic landmarks and five species of digital trees that can be seen along the route.”

Last month, it was revealed that Google App Engine would power the official site of the wedding.

The live stream of the wedding will begin at 9:00am GMT/5:00a ET on Friday, April 29 on the Royal Channel.

I’d expect plenty of photos on Flickr as well. The Royal Family launched its Flickr account last summer.
