Campaigning, like marketing, is all about attracting people and getting a message across, albeit for a different reason. In 2016, the New York subway was actually the next innovation in campaigning through the use of Scratch and Sniff. Angela H. Kim placed Scratch and Sniff posters around Canal Street, Union Square, and Herald Square stations to tackle the stench of the underground. the posters came with different scented tabs to “make your ride more pleasant”. The poster’s feature a strong message mimicking that of normal MTA announcements.
