The Associated Press (AP) is a major international news agency, providing news coverage, photographs, and video to media outlets worldwide. It was founded in May 1846, when six New York newspapers pooled resources to fund a relay of horses and riders to deliver news from the Mexican-American War. AP operates as an independent, no-profit news cooperative. Headquartered in New York, the organization serves member newspapers and broadcasters across the United States and maintains bureaus in nearly 100 countries. The cooperative has won 59 Pulitzer Prizes for journalistic excellence.
