The best essay written about product placement is by Mark Crispin Miller in his engaging anthology "Seeing Through the Movies." I believe Miller also has some association with the Center for the Study of Commercialization in Washington, D.C., which has made a number of statements on this issue. By the way, if you want to see a particularly egregious example of product placement, check out Ron Howard's lame newspaper film "The Paper." Coke plays such a prominent role I almost expected to see their name listed in the credits. Brian Rose Fordham University
