In the old days, the only “commercial” text normally found in toilet stalls and on urinal walls were those placed by anti-social cranks and hookers of various sexual orientations. Often using ballpoint pens as chisels, they scrawled phone numbers and crude taglines like “For a good time in Dallas, call…”
But in recent years, marketers like Sony Music, Unilever and Nintendo along with major liquor companies and TV networks have been systematically elbowing aside the hookers and cranks to get their own commercial messages in front of a demographic with its pants lowered and its zipper undone.
Deodorant brands, recording artists, video games and automakers are routinely buying space on the doors of toilet stalls or urinal walls. Meanwhile, other assorted “guerilla” media vendors offer condom packaging and urinal mats as relatively inexpensive messaging surfaces.
