Exxon Mobil

Available for over a year

America's biggest oil company, Exxon Mobil, earns more money every year than many entire economies. In the past it has stirred controversy by funding groups which deny the human race is causing climate change. Pulitzer prize-winning journalist and author Steve Coll has investigated the company and talks to Lesley Curwen about his book, Private Empire: Exxon Mobil and American Power. Plus, Mike Thomson reports on how Olympic sponsors are now protected by a British Act of Parliament. And Lucy Kellaway of the Financial Times presents a jaundiced view of the London Olympics, and workers' attitudes to Olympic transport disruption. (Image: the Exxon sign. Credit: AP Photo/Gene J.
