Americans are increasingly turning to online and radio sources for news and information, and are spending less time with daily newspapers and TV, according to (pdf) a media use and credibility survey commissioned by ARAnet and conducted by Opinion Research Corporation.

Daily newspaper usage dropped 4.1% and TV usage dropped 3.6%, while radio usage increased 2.9% and online usage increased 1.9%, the study found.

Credibility ratings for nearly all types of media except TV rose slightly from a year ago. TV is, however, still deemed to be most credible.

The national study of US adults, now in its second year, measured the percentage of news and information Americans receive from various media sources each month. Consumers reported getting 31% of their news and information from TV, and 19.4% from both radio and daily newspapers.

The media-use rankings from the survey, compared with last year’s results:

• Television: 31.1% (down from 34.7% a year ago)
• Daily newspaper: 19.4% (down from 23.5%)
• Radio: 19.4% (up from 16.5%)
• Online: 14.6% (up from 12.7%)
• Weekly community papers: 4.4% (down from 5.1 %)
• Free shopper newspapers: 2.9% (up from 2.2%)
• Magazines: 2.1% (up from 1.6%)

TV Drops Slightly, Still Most Credible

The was designed to gauge which media sources Americans view as the most credible sources of news and information. With the exception of TV, which dropped a tenth of a rating point, all media types stayed steady or increased slightly in credibility from a year ago.

The survey asked respondents to assign credibility scores to seven types of media, ranging from one for “not at all credible” to 10 for “extremely credible. Credibility scores:

• Television: 6.5 on a scale of one-to-10 (down .1 from a year ago)
• Daily newspaper: 6.3 (same as last year)
• Radio: 6.3 (up .3 from a year ago)
• Online: 5.7 (up .1)
• Weekly community papers: 5.4 (up .2)
• Magazines: 4.9 (up .3)
• Free shopper newspapers: 4.3 (up .8)

Other survey findings:

• College grads are more likely to trust online news (giving online a 6.3 rating vs. the 5.7 rating by the general population), and are less likely to trust TV news (giving TV a 6.1 rating vs. the 6.5 rating by the general population).
• Respondents with annual household incomes of $100K and above trust online sources considerably more than the general population (giving online a 6.5 rating, compared with the 5.7 rating by the general population).
• Higher-income respondents also view daily newspapers as more credible (6.8 vs. the 6.3 overall rating).
