Camel cigarettes is a cigarette brand introduced by R.J. Reynolds Tobacco (RJR) in 1913. Camels cigarettes contain a blend of Turkish tobacco and American tobacco. Camel cigarettes were blended to be considerably easier to cigarette smoke in contrast to the much harsher cigarette brands popular at the time of it's introduction. In addition, they were promoted, prior to official release, by a careful advertising campaign that included teasers which merely stated that (the Camel cigarettes are coming). This marketing style was, in fact, a prototype for attempts to sway public opinion that coincided with the United States entry into the First World War. The most famous variety of Camel cigarette was the soft pack of the regular, unfiltered variety. Camel regulars cigarettes achieved their zenith of their popularity through personalities such as actor Humphrey Bogart, who popularized the cigarette brand in such movies as Casablanca; the premium cigarette brand also gained notoriety through news broadcaster Edward R. Murrow, who smoked up to four packs of Camel cigarettes per day, in effect using a Camel cigarettes as his trademark. In late 1988, RJR created Joe Camel as the mascot for the cigarette brand. In 1992, the American Medical Association published a report stating that 5- and 6-year olds could more easily recognize Joe Camel than Mickey Mouse, FRed FlintstOne, Bugs Bunny or even Barbie.
