During that period, also, gun violence in movies doubled.
Is this trend continuing? Yes. Hollywood continues to rely on gun violence as a prominent element of "drama."
This study appears in Pediatric Perspectives, Jan 11, 2017.
Not only is it continuing, but the violence in PG-13s:
--Tthe consequences of it in these films--blood and suffering--seems to be erased more often.
--The violence may be largely bloodless, but still involve closeup executions, large-scale battles, and the death of innocent bystanders.
--And it is often perpetrated by comic book heroes and anti-heroes, making it a less realistic form of violence (like Wile E Coyote blowing himself up, for example).
Studies show that repeated exposure to violence can make some young people more aggressive. The effect of GUN violence is less well known at this point.
PG-13 movies now lead the box office.
The PG stands for parental guidance...Think about it.
