On thanksgiving day, think of the native sons and daughters of this land...may their spirits rest in peace. I always liked these commercials, sad as they were. More than four decades ago, the Ad Council partnered with Keep America Beautiful to create a powerful visual image that dramatized how litter and other forms of pollution were hurting the environment, and how every individual has the responsibility to help protect it. The ad, which featured Native American actor Iron Eyes Cody, "The Crying Indian," first aired on Earth Day in 1971. Created by ad agency Marstellar, Inc., the campaign used the line, "People Start Pollution. People can stop it." The ad became one of the most memorable and successful campaigns in advertising history and was named one of the top 100 advertising campaigns of the 20th Century by Ad Age Magazine.
