One of Cronkite's trademarks was ending the "CBS Evening News" with the phrase "...And that's the way it is," followed by the date. Keeping to standards of objective journalism, he omitted this phrase on nights when he ended the newscast with opinion or commentary. Beginning with January 16, 1980, Day 50 of the Iran hostage crisis, Cronkite added the length of the hostages' captivity to the show's closing in order to remind the audience of the unresolved situation, ending only on Day 444, January 20, 1981.
