The Associated Press is an American news agency. The AP is a cooperative owned by its contributing newspapers, radio and television stations in the United States, which both contribute stories to the AP and use material written by its staff journalists. Many newspapers and broadcasters outside the United States are AP subscribers, paying a fee to use AP material without being contributing members of the cooperative.
 
As of 2005, the news collected by the AP is published and republished by more than 1,700 newspapers, in addition to more than 5,000 television and radio broadcasters. The photograph library of the AP consists of over 10 million images. The Associated Press operates 243 news bureaus, and it serves at least 120 countries, with an international staff located all over the world.
 
Associated Press also operates The Associated Press Radio Network, which provides newscasts twice hourly for broadcast and satellite radio and television stations. The AP Radio also offers news and public affairs features, feeds of news sound bites, and long form coverage of major events.

Wikipedia: What’s Up, Doc? (Bugs Bunny short)
What’s Up, Doc? is a 1949 Looney Tunes cartoon directed by Robert McKimson and released by Warner Bros. Pictures in 1950 to celebrate Bugs Bunny’s 10th birthday that year, in which he recounts his life story to a reporter from “Disassociated Press”. Bugs talks about his birth, his rise to fame, the slow years, and when famous Vaudeville performer Elmer Fudd chooses him to be part of his act. Eventually the duo comes upon their classic formula of Hunter vs. Hare.

Last Saturday night the comical Disassociated Press asked us if we could furnish them with anything on the Markesan murder which is on the other side of the state and we felt like the fellow who was asked if he could change a hundred dollar bill.

Going My Way:
Bing Crosby and American culture
By Ruth Prigozy and Walter Raubicheck
Rochester, NY: University of Rochester Press
2007
Pg. 131:
Playing against the notion of Crosby’s status in the pantheon of American show business and culture, but referring to Crosby’s earlier obscurity at the beginning of his career, is Robert McKimson’s 1950 short What’s Up, Doc? In this film, Bugs Bunny is seen as a wildly successful movie star, complete with Hollywood-style sunglasses, and as he chews on carrots from a fancy cigarette case he is asked by the “Disassociated Press” to tell his life story.
