Cronkite reported many events in his career, including bombings in World War II, the Nuremberg trials, combat in the Vietnam War, Watergate, the Iran Hostage Crisis, and the assassinations of President John F. Kennedy, civil rights pioneer Martin Luther King Jr., and Beatles musician John Lennon. He was also known for his extensive coverage of the U.S. space program. Considered universally the dean of broadcast news, he is known for his departing catchphrase, "and that's the way it is", followed by the date of the broadcast. The phrase was often used in parody.
Perhaps due to his low register voice, his mustache, and his comforting tone, in certain circles, he was affectionately referred to as "Uncle Walter." Cronkite served in an era when politically biased reporting was kept under wraps. His political leanings became a bit more forthcoming after leaving his anchor post.
