The Television News Archive collection at Vanderbilt University is the world's most extensive and complete archive of television news. The collection holds more than 30,000 individual network evening news broadcasts from the major U.S. national broadcast networks: ABC, CBS, NBC, and CNN, and more than 9,000 hours of special news-related programming including ABC's Nightline since 1989. These special reports and periodic news broadcasts cover presidential press conferences and political campaign coverage, and national and international events such as the Watergate hearings, the plight of American hostages in Iran, the Persian Gulf war, and the terrorist attack on the United States on September 11, 2001. Material in the archive can be identified for use through the TV-NewsSearch Database. In addition, through its detailed content related to news events, this resource also serves as a unique reference tool for studying historical and political events.
