According to Microsoft, the July 7, 2007 Live Earth concerts streaming on MSN.com made history with more than 8 million people watching over 15 million streams, with peak simultaneous viewership of 237,000 people.

The company claims that, to date, more than 30 million people witnessed some portion of the event online. The peak simultaneous viewership was during Madonna’s performance in London.

Live Earth television ratings, on the contrary, did not fair so well. Nielsen Media Research reported that only 2.7 million people watched the event last Saturday and was ‘least watched’ compared to other shows aired opposite it: ABC’s America’s Funniest Home Videos, CBS’ 48 Hours Mystery, and Fox’s America’s Most Wanted.

Here are some videos from Live Earth 2007:

Madonna - Hey you

John Mayer - (Not) Waiting on the world to change

The Police - Message in a Bottle

Shakira - Hips don’t lie
