The original 1billionhungry campaign borrowed as its slogan the line "I'm as mad as hell, and I'm not going to take this anymore!", used by Peter Finch in the 1976 film, "Network". Meanwhile, the yellow whistle has been the campaign symbol from the start, from 1billionhungry to Ending Hunger. (The creative concept was provided by the McCann Erickson Italy Communication Agency.) It symbolizes the fact that we are "blowing the whistle" on the silent disaster of hunger. It is both a symbol and – at many live events taking place around the world – a physical means of expressing frustration and making some noise about the hunger situation.
