David Muir took the helm of World News Tonight in 2014, transforming it into America's dominant evening broadcast with consistent No. 1 rankings in total viewers for the 10th straight year, averaging over 8 million nightly and widening leads against NBC and CBS competitors. His on-the-ground reporting from global flashpoints has garnered multiple Emmy and Murrow honors, complemented by high-profile exclusives and moderating the 2024 presidential debate for 70 million Americans. Though headquartered in New York, Muir's coverage frequently zeroes in on South Florida's urgent stories, including Miami hurricanes and coastal vulnerabilities. In 2026, his program notched nearly 9 million viewers during Olympic weeks and secured its largest seasonal margins in decades.
