The Royal Wedding to break records - and the Internet?

(CBS/What's Trending) Predicted to draw in 2.5 billion viewers, the Royal Wedding could be the largest televised event of all time and use more bandwidth than any live stream in history. With an estimated 700 online million viewers in the wings -- 400 million of which are on YouTube alone --there's concern over whether the impending nuptials of Prince William and Kate Middleton may cause an Internet meltdown. However, any fear of short-circuiting the web, isn't dissuading the digital audience. According to the Internet research firm Greenlight, Flickr, Twitter, and Facebook fans are flooding the interwebs with at least 9,000 comments a day on the topic, which is currently being mentioned every 10 seconds online.

To give you some perspective, the largest simultaneously-watched YouTube event to date was the U2 Rose Bowl concert, which 10 million people watched together online in November 2009. Extreme Tech figured it would take 800 million megabits of data transfered per second. As PC Mag puts it, that's about 80 million times the transfer rate that's possible through a typical home Internet connection.

But, we're betting you still want to join the streaming parties. Here's how to enjoy the nuptials online.

The Royal Wedding YouTube channel, powered by Google, will cover the event for four hours from 10AM London time/5AM EST. In addition to streaming the ceremony, the channel will feature live commentary, historical information and the procession route.

Viewers can upload messages of congratulations to the official video "Wedding Book."

Multiple news outlets are streaming live coverage of the event, as well. These include BBC, ABC News, Fox News, CBS News, AP Live, ET & Insider.com, and the U.K. Press Association.

If you'd prefer to live stream the event on your blog, you can do so for just $250. It's not to late to register, but the clock is winding down. 

Can't stand the fact you won't be able to see the event in person so you refuse to watch any of the feeds? Read about the wedding at the Clarence House Twitter stream.

As the countdown to the ceremony ticks on, fans around the web are paying tribute to the British couple. An a cappella group of 11 Scottish men, known as The Other Guys, created this viral pop parody.
