In broadcast journalism, late-breaking refers to news that is breaking immediately after the main programming of a television or radio program, such as an accident, a political scandal, a natural disaster, or an urgent national security alert. The term is used most often on 24-hour news channels where a live anchor can interrupt programming for the most pressing of stories, such as the assassination of President John F. Kennedy, although cut-ins and alert crawls are used as well on other traditional news networks and local stations.
A recurring feature on many news shows is a ticker of the latest late-breaking headlines, which may be highlighted with special lower third graphics to convey urgency or prominence. In addition, the term can also be applied to a news segment that is presented shortly after the end of the regular program, such as weather forecasts or traffic updates.
LBW submissions must report data that became available for public dissemination after the deadline of the regular abstract submission (including the CHI 2025 e-poster abstract submission) and are of critical importance to the scientific/clinical community or the general public. These works should be unique, and not an extension of previously published work.
