Early Years and Origins
CBS Evening News began on May 3, 1948, as CBS Television News. It started as a 15-minute program and was one of the first regularly scheduled television news broadcasts in the United States. Douglas Edwards served as the first anchor and helped establish the format for evening news programs. The early broadcasts were simple compared to modern news, with Edwards reading stories and showing film footage of events.
The Walter Cronkite Era
Walter Cronkite became the anchor in 1962 and remained with the program for 19 years until 1981. During his tenure, the program expanded to 30 minutes and became the most-watched evening news broadcast in America. Cronkite covered major historical events including the Kennedy assassination, the Vietnam War, the Civil Rights Movement, and the moon landing. He became known as the most trusted man in America and made the CBS Evening News the leading news program.
Growth and Evolution
After Cronkite retired, Dan Rather took over as anchor from 1981 to 2005. The program continued to be a major news source during this period, covering important events like the Challenger disaster, the fall of the Berlin Wall, and the Gulf War. The broadcast adapted to new technology and changed its format multiple times to remain relevant to viewers.
Modern Era
Since 2005, CBS Evening News has had several anchors including Katie Couric, Scott Pelley, and Norah O'Donnell. The program has adjusted to compete with cable news and internet news sources by maintaining high journalistic standards. Today, it airs on CBS television and is also available on the Paramount Plus streaming service.
Cultural Impact
CBS Evening News helped establish television as a primary news source for Americans and set standards for how evening news programs are structured and presented. The program's success led other networks to launch their own evening news broadcasts. Many of its anchors, especially Walter Cronkite, became cultural icons and trusted figures in American households.
