The movie ratings system was designed in part to prevent young children from being exposed to inappropriate content, but nowadays it's easier than ever for kids to watch R-rated movies -- and they don't even have set foot inside a movie theater.
The advancement of technology has made it simple for children to watch R-rated movies. Those are the films that have so much sex or violence -- or other adult-themed content -- that those who are 17 and under may only see them if they're with a parent or adult guardian.
Children can order movies on demand through their home's cable service provider. They can order them through their video gaming system, or get them through Netflix, YouTube or Hulu.
Some of the services are free. For others, though, they need a credit card.
"The thing is, it doesn't really matter what your age range is," 13-year-old Tyler Lynch, a New Jersey resident, told "Good Morning America." "It just matters if you have the money."
That way is far easier than the age-old ploy of trying to sneak one's way into an R-rated film at the multiplex. For the so-called Net Generation, that gambit is old-fashioned.
"It's a lot more to deal with. People still check IDs and stuff like that," said 14-year-old Kathleen McGrath, also of New Jersey.
While some children may not think twice about ordering up an R-rated film -- and many do so with their parents' permission -- experts fear that exposing developing minds to certain content may have harmful effects.
Studies have indicated that showing adult content to children can increase violent behavior, but recent investigations have also revealed that showing R-rated movies to children can encourage them to experiment with drinking and smoking.
"Today you can sit in the privacy of your own room, or in a family room, and download something on your cell phone or over the Internet," said Jim Steyer, founder and CEO of Common Sense Media, a national organization that reviews movies for age-appropriateness and which also provides advocacy and outreach.
"You can be exposed to inappropriate content without ever having to come near a movie theater," Steyer added.
Erna Nalic, 14, says her parents are "pretty lenient," and may let her watched an R-rated movie if they watch it before she does.
Tyler says he only watches R-rated films if his parents allow it.
Asked if he ever sneaked a film in without their knowledge, he admitted that he had.
"Maybe once or twice, just, you know," he said. "Sometimes my parents are out and I order a movie rated R and I won't tell them about it. I don't think they've ever caught me."
But an occasional sneak-peek isn't what most parents worry about -- or should worry about, Steyer said. Rather, it's the constant onslaught of images from sources they often feel they can't control. On the Common Sense Media website, parents vent about easily available R rated movie previews, for example. Although theaters don't air them in PG movies, they are all over the internet, and even air routinely on some cable system's on-demand menu pages.
The solution? Do your homework, says Steyer. It will pay off.
