NBC News pioneered the morning news program when it launched TODAY more than 55 years ago, with Dave Garroway as host. The live broadcast provides the latest in domestic and international news, weather reports and interviews with newsmakers from the worlds of politics, business, media, entertainment and sports. After more than 48 years of the standard two-hour format, the third hour was launched in October of 2000, followed by the fourth hour in September 2007, making Today the only four-hour hour national morning show broadcast. The program is unparalleled in its ratings dominance in the morning news arena, serving as America's overwhelming favorite for more than an unprecedented eleven consecutive years.

Since the program’s premiere broadcast on January 14, 1952, Today’s hallmark has been its ability to revise an entire edition to bring viewers breaking news as it happens. In that fashion, Today delivered immediate coverage of such events as Hurricane Katrina and its aftermath, the Tsunami that wreaked havoc in a dozen Asian nations, the September 11 terrorist attacks on the World Trade Center, the death of John F. Kennedy, Jr., the tragic high school shootings in Littleton, Colorado, the crash of TWA Flight 800, the death of Princess Diana, and the Oklahoma City bombing and trials.
