Washington (AFP) - Americans are increasingly turning to their mobile devices for news, with print newspapers losing more ground, a poll showed Thursday.

The Pew Research Center survey found an acceleration in the use of mobile devices for news over the past three years, as fewer Americans relied on newspapers. Television meanwhile held steady as a source of news, including local, network and cable.

The portion of Americans who get at least some news on a mobile device rose to 72 percent in 2016 from 54 percent in 2013, Pew said. That included 36 percent who said they "often" get news from a smartphone or tablet.

The survey confirmed the trend toward digital and mobile while offering a grim outlook for the newspaper sector, which is failing to connect with young adults.

Just 20 percent of adults said they often got news from print newspapers, compared with 27 percent three years earlier.

Overall, eight in 10 respondents said they got at least some information from newspapers, little changed from the previous survey.

But the demographics for newspaper readership were especially challenging: just five percent in the 18-29 age group said they often read newspapers, compared with 48 percent in the over-65 age group.

The findings for young adults are "very stark" when it pertains to "holding a print edition," said Pew researcher Jeffrey Gottfried, but less dramatic when it comes to getting news from many of those same organizations online.

"Younger people are getting news online at even higher rates than older Americans," he said.

News still is important to Americans: More than seven in 10 follow local and national news closely, and 65 percent monitor international news with the same regularity.

Fully 81 percent of Americans get at least some of this news through websites, apps or social networking sites, with the mobile share growing.

Television remains a major source of information, with 57 percent of adults often getting TV-based news. The survey found little change in reliance on local and national TV news broadcasts, and an increase in the percentage watching cable news.

"Americans do have a preference for getting news on a screen, but it is television that still dominates," Gottfried said.
