Don’t think that watching only broadcast television will protect your kids from the violent content that is often aired on cable television shows. Or that there is any difference in the violence in a PG-13 movie and one rated R.
New research from the Parents Television Council found that the volume and degree of violent content shown on broadcast and cable television are virtually indistinguishable; and that broadcast TV shows in the study consistently underrated graphically-violent content as appropriate for 14-year-old children, even though similar content on the cable networks was rated for mature audiences only.
