The Philadelphia Inquirer and Philadelphia Daily News ran a fake ad campaign within their Friday editions to "demonstrate the power of our brands in generating awareness and generating traffic for our advertisers, and put a smile on people's faces."

According to Philly.com the Friday editions contained blue banners throughout the papers , as well as on their Web site, Philly.com, Derrie-Air cheerily trumpets its policy: The more you weigh, the more you pay. The ads direct readers to the Web site http://www.flyderrie-air.com.

Visitors who scroll to the bottom of Flyderrie-air.com see a disclaimer that reads, "The Derrie-Air campaign is a fictitious advertising campaign created by Philadelphia Media Holdings to test the results of advertising in our print and online products and to stimulate discussion on a timely environmental topic of interest to all citizens."

Quoted in an Editor and Publisher article, Bob Steele, the Nelson Poynter Scholar for Journalism Values at The Poynter Institute said "It is clearly deception. Newspapers should not be in the business of deception. I can’t imagine the Inquirer and Daily News would run fake ads from other companies."

In the same article Kelly McBride, Poynter ethics group leader, said, "Market research is a good goal in terms of understanding how advertising is going to work in this era. I wonder if there is a way to do that that doesn't deceive the audience. Is there something you could create that could measure responses without tricking the audience?"
