The NBC Nightly News is the flagship daily evening television news program for NBC News and is the #1-rated newscast in America. NBC Nightly News airs live from Studio 3B in NBC Studios at 30 Rockefeller Center. Currently, weekday broadcasts are anchored by Brian Williams, and weekend editions are anchored by Lester Holt. On weeknights, it is broadcast live over most NBC stations from 6:30-7:00 PM Eastern and occasionally updated for Pacific Time Zone viewers in a 'Western Edition'. Its current theme music was composed by John Williams. The Huntley-Brinkley Report was renamed NBC Nightly News in August 1970 upon the retirement of Chet Huntley. At first, David Brinkley, John Chancellor, and Frank McGee formed a rotating troika, only two of whom anchored the program on a given night. Each evening's program included one news anchor in New York and one in Washington, as had been the case on Huntley-Brinkley.
