Summer has always been a profitable season for Hollywood, as millions of people buy tickets to see new blockbuster movies.
But this summer is also a time of worry and fear for America's film studios, because the pirates of the Internet are gaining on them.
Almost every new film can now be found on the Internet -- and downloaded for free as soon as it's released, and sometimes even before.
As Correspondent Lesley Stahl first reported last year, it may be illegal, but it's becoming easier and easier to do. The people running America's movie studios know that if they don't do something - fast - they could be in the same boat as the record companies.
But what's really at stake for the movie industry with all this piracy?
“Ultimately, our absolute future,” says Peter Chernin, who runs 20th Century Fox, one of the biggest studios in Hollywood.
He knows the pirates of the Internet are gaining on him.
“I think it's probably in the hundreds of thousands, if not millions,” says Chernin. “It's only gonna grow. Somebody can put a perfect digital copy up on the Internet. And with the click of a mouse, send out a million copies all over the world, in an instant.”
And it's all free. Chernin organized a "summit" between studio moguls and some high school and college kids -- the people most likely to be downloading.
“And we said, ‘Let's come up with a challenge,'” says Chernin. “Let's give them five movies, and see if they can find them online. And we all sat around and picked five movies, four of which haven't been released yet. And then we came back half-an-hour later. They had found all five movies that we gave them.
