Smokey Bear is an American campaign and advertising icon created by the U.S. Forest Service with artist Rudolph Wendelin. In the Wildfire Prevention Campaign, which is the longest-running public service announcement campaign in United States history, the Ad Council, the United States Forest Service (USFS), and the National Association of State Foresters (NASF) employ Smokey Bear to educate the public about the dangers of unplanned human-caused wildfires. A campaign began in 1944 featuring Smokey and the slogan “Smokey Says – Care Will Prevent 9 out of 10 Forest Fires”. His slogan changed to “Remember… Only YOU Can Prevent Forest Fires” in 1947 and was associated with Smokey Bear for more than five decades.
