The Camel News Caravan or Camel Caravan of News was a 15-minute American television news program aired by NBC News from February 14, 1949 to October 26, 1956.
 Sponsored by the Camel cigarette brand and anchored by John Cameron Swayze, it was the first NBC news program to use NBC filmed news stories rather than movie newsreels.
 On February 16, 1954, the "Camel News Caravan" became the first news program broadcast in color, making use of 16mm color film.
 In early 1955, the R.J. Reynolds Tobacco Company, maker of Camel cigarettes, cut back its sponsorship to three days a week.
 Chrysler's Plymouth division sponsored the other days, and on those days, the program was labelled the "Plymouth News Caravan".
 The program featured a young Washington correspondent named David Brinkley, and competed against "Douglas Edwards with the News" on rival CBS.
 With greater resources, the "News Caravan" attracted a larger audience than its CBS competition until 1955.
The 1973 Camel GT season was the 3rd season of the IMSA GT Championship auto racing series.

 It would also be the only time IMSA GT would leave northern North America (i.e. the United States and Canada).
