Bill Moyers hosted a documentary on the U.S. Public Broadcasting Service (PBS) that follows several Washington Post reporters as they investigate farms subsidies in the United States. The 2006 Washington Post investigation resulted in a series of articles that uncovered vast flaws in U.S. agricultural subsidies. The journalists were recently awarded six Pulitzer Prizes.
