In 1977, William S. Doyle, Deputy Commissioner of the New York State Department of Commerce hired advertising agency Wells Rich Greene to develop a marketing campaign for New York State. Doyle also recruited Milton Glaser, a productive graphic designer to work on the campaign, and created the design based on Wells Rich Greene’s advertising campaign. Glaser expected the campaign to last only a couple months and did the work pro bono. It was possibly inspired in part by the state tourism slogan Virginia is for Lovers which had featured a “Love” theme and red heart symbol (♥) since1969. The innovative pop-style icon became a major success and has continued to be sold for years. In the popular mind (though this was not the original intention) the logo has become closely associated with New York City, and the placement of the logo on plain white T-shirts readily sold in the city has widely circulated the appearance of the image, making it a commonly recognized symbol.
