A history-making audience of viewers from around the world united at MSN to watch the Live Earth concerts and confront the threat of global warming.

Since the start of the first Live Earth concert in Australia, MSN has delivered:

• More than 15 million streams during the live coverage (so 24 hour period) by a total of 8 million people

The U.K. concert at Wembley Stadium was the most watched live stream, and peak simultaneous viewership of 237,000 occurred during Madonna's closing performance in London. Other popular artists throughout the day included Kelly Clarkson, Metallica, Red Hot Chili Peppers, Rihanna and Shakira.
