　　In a world full of free information, some young people are still willing to pay for news they read.

　　A recent study shows that 40 percent of U．S. adults aged 18－34 pay for at least some of the news they read, whether it's a printed newspaper or a digital (数码的) news app. Another 13 percent don't pay themselves but depend on someone else's subscription (订购), according to the Media Insight Project. Older ones are more likely than younger ones to personally pay for news.

　　"Forty percent is a strong number, but that means many people are still not willing to pay，" said Professor Keith Herndon. "We have to think of ways of making the news attractive enough so that someone would be willing to pay for it."

　　The increasing amount of free news online and new ways for advertisers to reach more people has worried publishers of newspapers and magazines. Newspapers' print ad revenue (收入) has dropped 63 percent, to $16.4 billion, in 2014 from 2003, according to Pew Research Center. Daily paid newspaper circulation reached its highest point in 1984, at 63.3 million, according to an industry group. That was a quarter of the country's population. Daily paid newspaper circulation has now dropped to 40.4 million, even as the U．S. population has grown by about a third.

　　There have been efforts (努力) to make the best use of digital ads. Digital ad revenue from newspaper websites has more than doubled as print ad revenue dropped, but still come to only $3.5 billion. And in recent years some major news organizations have begun charging for entering their websites and selling digital­only subscriptions, rather than posting news for free online. For example, The New York Times lets non­subscribers read a certain number of articles per month before they have to pay.
