POST advertising is an embedded element of the urban landscape of New York City. Comprised of a variety of marketing practices, it includes signs on the insides and outsides of retail stores, and has a more immediate and comprehensive effect on tobacco sales than any other marketing channel \citep{rj1994}. There is substantial evidence of disparity in the way tobacco products are advertised at the point-of-sale depending on the community demographic profile of focus. Tobacco manufacturers have long targeted minority and lower income populations in particular, mainly through this sort of tailored advertising \citep{Seidenberg_2010}. The goal of this project is to map POST marketing practices across New York City (NYC) using an automated method of detecting and classifying tobacco signage \citep{Cao2010}. In comparing the POST landscape with socioeconomic characteristics at the neighborhood level, we also aim to explore marketing disparities and variable exposure of communities to tobacco advertisements.
