Younger Americans, having abandoned print news sources like Newsweek, are now dumping TV news in favor of computers and smartphones to give them the daily headlines.

In a shocking new poll sure to shake up the news industry, the Winston Group revealed to Secrets that 57 percent of Americans aged 18-34 get their news from computers, with TV being the delivery source for just 33 percent. Smartphone use is a close third at 24 percent, said pollster David Winston.

And it's not just younger Americans who are shifting away from TV news. Middle-aged Americans, 35-44, are also sitting in front of the computer more often. Winston said that 50 percent get their news from TV, while 48 percent click through stories online. And 18 percent use smart phones to check up on the presidential race and World Series.

When the full public, including older Americans, is included in Winston's poll sample, TV still has the edge. Some 58 percent of all respondents polled get news from TV, 41 percent from computers, 15 percent from the radio, 11 percent from smartphones, and 7 percent from their iPad or other tablet.

But the change to computers and mobile devices is clearly coming for the news media, Winston found.

"Among the 'Overall' responses, television was still the most popular device, but computers were a reasonably close second, well ahead of radio. Additionally, radio is beginning to see some stiff competition from smartphones," said Winston.

"But the advantage in audience size that television has over computers and the lead that radio has over smartphones disappears when you look at younger members of the population. Among 35-44 year olds, smart phones and tablets are already outpacing radio as a source of news. When you look at 18-44 year olds, the results are even more striking with computers dominate as a source of news, outpacing television, with smartphones beginning to challenge for second spot.

"There can be no doubt that the media landscape has already changed for the youngest members of the adult population."
