Over the years, people working for one cause or another have found many ways to get their message out. They have used posters, speeches, television commercials, and the internet. More recently, a new and unusual way of getting a message out has developed - huge, worldwide concerts.
This method was used in 1985 with the Live Aid Concert that raised money to help famine-stricken countries. Live Aid included concerts that were held in several locations around the world. Satellite transmissions and simultaneous television broadcasts opened up the event to millions of viewers. An even bigger concert, Live 8, was held in 2005, also in support of the world's poorest countries.
In 2007, another massive event was staged. This one, called Live Earth, was held to support the environment. It may have been the largest global entertainment event ever. The pop and rock concerts took place over twenty-four hours and on seven continents. The event was billed as the "Concerts for a Climate in Crisis." Concerts were held in New York, London, Sydney, Tokyo, Shanghai, Rio de Janeiro, and five other locations. The concert in Antarctica had one band performing for seventeen audience members.
Performers, including legendary rock stars as well as rising stars, filled stages around the world. The performers included The Police, Bon Jovi, Kanye West, Kelly Clarkson, and The Black Eyed Peas.
