NEW: Study: Erratic TV violence ratings fail parents

LOS ANGELES (AP) — A new
study says that violent dramas on the broadcast networks carry milder
cautions than cable shows that are equal in gore.

The Parents
Television Council study released Monday says that graphic violence on
network series invariably received a TV-14 label, or “parents strongly
cautioned.”

But similar fare on cable shows typically was given the most stringent label, TV-MA for mature audiences only.

Episode
ratings are decided by networks and cable channels, similar to how the
movie studios' Motion Picture Association of America self-governs by
issuing its own movie ratings.

The board that oversees TV ratings uniformity defended the system as a “valuable resource” for parents.
