At the same time, the New York State Department of Health aired a separate, simultaneous statewide television-based antitobacco media campaign that also targeted New York City, with advertisements featuring graphic images of the effects of smoking and highlighting the effects of secondhand smoke on children. From January through December 2006, New York City adult smokers were exposed to nearly 11,000 GRPs as a result of both campaigns combined, equating to the average viewer in NYC seeing an advertisement approximately 110 times during the year.
