 From ABC's "World News Now" to "Countdown with Keith Olbermann", many have attempted to imitate "Overnight"'s signature style of combining hard news features with incisive commentary and light hearted stories.The Seven Network in Australia had a similar program with the same name (minus the NBC) airing overnights on weeknights between 1985 and 1989.Clips from NBC News programs would often be shown within the show.
