Google's left-leaning media bias revealed: Academic study exposes how search engine massively over-promotes results from liberal news websites over right

Google's bias towards left-wing media outlets has been laid bare by an algorithm which detected that it favors sites including CNN and The New York Times over others.

According to data compiled by researchers from Northwestern University, the search engine promoted those sites over others repeatedly in November 2017.

Of the 6,302 articles that appeared in Google's 'top stories' page that month after a term was searched, more than 10 percent were by CNN.

The New York Times was the second most favored and accounted for 6.5 percent of articles. The Washington Post was third with 5.6 percent.

By contrast, Fox News, the most right-wing outlet in mainstream media, was the source of just three percent of the stories which appeared.
