When a new story is extremely important and must be reported immediately, it is called late-breaking. Breaking news typically requires an interruption of programming to report the information, but at 24-hour news networks with anchors available live for immediate interruption, breaking news can also be reported in the middle of regular programming using lower thirds and other graphics to convey urgency. In the days before 24-hour television, interrupting programming for breaking news was reserved for severe and imminent threats such as tornadoes or landfalling hurricanes.
Late-breaking works (LBW) are research developments that may not have been published or presented in time for the CHI 2025 submission deadline, but are highly significant and of critical importance to the field. LBWs report on data that became available for public dissemination after the CHI abstract submission deadline, and must be substantially novel (not simply an extension of existing work) or definitively confirm or refute other critically important work. Accepted LBWs will be presented in the LBW session at CHI 2025 and appear semi-archival in the ACM Digital Library.
