In a move to combat the epidemic of false and unreliable information on the internet, Google is pledging to spend $300 million over the next three years to support authoritative journalism.

Google’s campaign, which was announced at an event in New York on Tuesday, will be known as the Google News Initiative. Among the initiative’s goals are making it easier for Google users to subscribe to news publications, and giving publishers new tools to create fast-loading mobile pages. The project is Google’s most ambitious attempt yet to improve the quality of information it shows to users at a time when tech companies have come under criticism for letting hoaxes and misinformation bloom on their services.

Philipp Schindler, Google’s chief business officer, said in a blog post that the initiative was intended to signal the company’s “commitment to a news industry facing dramatic shifts in how journalism is created, consumed and paid for.”

As part of its efforts, Google is helping to create a Disinfo Lab in partnership with the Harvard Kennedy School’s First Draft, which will attempt to identify false news during critical breaking news situations. Google and YouTube, the video site owned by Google’s parent company, have been criticized for allowing conspiracy theories and unreliable partisan sources to filter to the top of search results for breaking news and for having failed to stop the spread of false news during the 2016 presidential race.
