According to the poll, 57 percent of Americans say they do not trust the news of the US mass media. The figure released on Wednesday shows a record high, up from 56 percent last year.
The poll, with the maximum margin of sampling error of ±4 percentage points, gathered information from 1,019 adults, aged 18 and older, from between September 13 to16.
Nearly 63 percent of those polled perceive bias in media and political news outlets in one direction or the other.
The report further added that the public trust in the media is now even lower than its trust in the executive and judicial branches of the US government.
Gallup's annual Confidence in Institutions survey published on August 15 found that 75 percent of the respondents do not have confidence in newspapers, with 78 percent distrusting television news.
Experts say the US media are not gaining new fans as Americans continue to express low confidence, in line with the steady slide over the past two decades.
The results also reflect the rise of alternative media and Internet news sources, which are rapidly gaining popularity among Americans.
