Recent research suggests that advertisements that run during violent or sexually explicit programs are less likely to lodge themselves in a viewer's memory than advertising that runs during other kinds of programs.
That is, viewers are less likely to be able to recall those brands immediately after the show, as well as the next day.
Viewers are about twenty percent less likely to remember a brand, however it is advertised, when it airs during a violent or sexually explicit program.
Generally, brands that advertise with violence are about twenty-seven percent less memorable than brands that advertise in sexual or more neutral forms. What it boils down to is that sex and violence do not sell after all.
