Adding to Ads

This post on Core77 about "product re-placement" is similar to things I'm seeing a lot of on design blogs lately. A number of artists are finding ways of replacing or altering ads in public spaces in order to "reclaim" these spaces for art, communication, or satire. One recently publicized example is Poster Boy, the New York-based "artist" who literally cuts and pastes pieces of subway advertisements onto one another to create new, often humorous pieces. It seems the public is growing tired of the increasingly invasive advertising industry's efforts to sell products and services, and instead of quietly absorbing them, people are defacing, adjusting, or otherwise creating new messages and visuals to absorb. It will be interesting to see how the advertising industry deals with this threat; my thought is that those who are smartest will work with, and not against, this trend.
