Bob Geldof promised us the greatest concert ever. In London's Hyde Park, hundreds of thousands of people gathered to see if he could pull it off. Live 8 also demonstrated the power of technology to influence a global agenda by using SMS message lotteries to allocate tickets, to interlink concerts via large monitor video feeds and create an illusion of interconnectedness, to distribute messages through downloads and video streams and to express political opinion through text messages sent from cellular phones. It captured the high moral ground on the humanitarian crisis of the moment: poverty in Africa. Technology sent an activist message around the world. Unfortunately, so did the bombs.
