I Love New York (stylized I NY) is a slogan, a logo, and a song that are the basis of an advertising campaign developed by the marketing firm of Wells, Rich, Greene under the directorship of Mary Wells Lawrence used since 1977 to promote tourism in the state of New York, including New York City. The trademarked logo, owned by the New York State Department of Economic Development, appears in souvenir shops and brochures throughout the state, some licensed, many not. "I Love New York" is the official state slogan of New York. The logo was designed by graphic designer Milton Glaser in 1976 in the back of a taxi and was drawn with red crayon on scrap paper. The original drawing is held in the Museum of Modern Art in Manhattan. The song was written by Steve Karmen and its copyright was donated by him to the state. The logo consists of the capital letter I, followed by a red heart symbol (), below which are the capital letters N and Y, set in the rounded slab serif typeface American Typewriter. 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 create a design based on Wells Rich Greene's advertising campaign. Glaser's initial sketch to accompany the agency's "I Love New York" slogan was conceived in a taxi. It comprised the letter I and a heart shape followed by NY, all on the same line. As the idea developed he decided to stack the I and heart shape on a line above the NY characters, later stating that he may have been "subliminally" influenced by Robert Indiana's LOVE pop art image. Glaser expected the campaign to last only a couple months and did the work pro bono. The innovative pop-style icon became a major success and has continued to be sold for years.
