Sex and the Movies

Sex is once again used to sell something......movies. Some form of sexual cotent is found in alot of movie trailer and previews and this is fact because of the study done by oliver and kalyanaraman. In fact "on average the previews contained 1.51 sex scenes per minute" and that's alot of sex for a 30 second to three minute clip. Obviously the whole movie doesn't have that much sex in it and the producers can choose to put anything they want in the previews and trailers, but why do they always choose to show the sex. The movie industry is a multi billion dollar industry and whatever producers are doing is working becuase lots of movies are still being made. And they ae being viewed because of sex. In addition to movies promoting sex to sell themselves, it seems like the sexual portrayals tend to be about woman. Some it extremly short skirts such as in Empire records and other in other ways csuh as bathing suits or in a bed, as eluding to the fact that sex has just happened or is about to occur. Why can't the previews just tell what the movie is about without all the sex.
