"Breaking News" is a term used in journalism that implies a recent and typically sudden news development. A story that is designated “breaking news” interrupts normal radio, television, and sometimes Internet broadcasting or publishing with a live report on a significant incident.
Historical events such as the bombing at Pearl Harbor, the stock market crash of 1929, the assassinations or assassination attempts on U.S. and world leaders, have all been considered breaking news. Other events that are not tragedies or disasters have also broken regular programming such as news in space exploration (the Apollo 11 moon landing in 1969), certain sporting events, and the outcome of the O.J. Simpson double murder trial.
