From KCRW and KCRW.com, I'm Kim Masters, and this is the business.

You listen, if you listen and learn, then you're going to be able to do anything you want

next time.

This week on the business, veteran TV writer Linda Bloodworth-Thomason talks about her emotional

documentary in support of gay marriage and her significant work as an image maker for her longtime friends, Bill and Hillary Clinton.

She may have helped Bill win the presidency, and she's ready to do it again for Hillary.

I did her Senate campaign film, and then I did her bow, when she bowed out of the presidential race in 2008.

I wanted her to walk up that stage in an exuberant way, you know, and this is a new beginning. And we don't

know what it's going to be yet, but it's a new beginning. But first on the Hollywood

news banter, a new study shows PG-13 movies are more violent than R-rated films. Stick

around. It's the business from KCRW. I am joined by my banter buddy,

John Horn of the Los Angeles Times. Hello, John. Hello, Kim. So, John, we have a new study,

which may confirm what certainly you and I, I believe, have long suspected and known in our guts,

which is that the PG-13 rating has become increasingly tolerant, let's say, the MPAA, which is overseeing

this, their ratings board, has become increasingly tolerant of violence in PG-13 ratings

to the point where these movies are now more violent than R-rated movies.

Yeah, tolerance, one word, blind might be another. This is a very comprehensive study that

looked at almost a thousand films. It went all the way back to 1950, but the specific area they were

studying is 1985 to the present, 1985 being the first full year in which the PG-13 rating was

enforced. And what they found is that gunplay tripled in that period from 1985 to the president.

And as you said, in 2009, PG-13 films caught up with R-rated films and level of violence per hour.

And in the last couple of years, it's actually been higher.
