WASHINGTON (CBSDC) — Online outlets are the number one source of news in the United States, surpassing both television and print, according to a new study.

The Reuters Institute Digital News Report 2015 found that 43 percent of Americans identified online sources as their “main source” of news, as reported by Tap Into. Television trails slightly behind with 40 percent of Americans citing it as their main source of news.

Research indicates that seven out of ten magazines have lost subscribers in recent years. About half of news magazines analyzed received more visits via mobile devices than desktops, according to Pew Research Center. The Pew study also found that print newspapers continue to struggle with circulation dropping 3 percent from 2013 to 2014.

The new Reuters study suggests that mobile news and video news consumption online are experiencing substantial growth.

“We see the smart phone more clearly as the defining device for digital news with a disruptive impact on consumption, formats, and business models,” Nic Newman, Research Associate, Reuters Institute, notes.

The U.S., United Kingdom, and Japan showed the most growth in news accessed via smartphones. Average weekly usage has grown from 37 to 46 percent across all countries, with two-thirds of smartphone users  now accessing news through their devices every week.
