Google extends fact-checking to image search

SAN FRANCISCO - Alphabet Inc's Google on Monday said it would start showing fact-checking labels on Google Images search results globally, as tech companies come under increasing pressure to combat the viral spread of misleading claims online.

Google will display the "fact check" labels underneath thumbnails that appear in image search results along with a summary of third-party fact-checkers' findings, as it already does on its general search engine and on Google News results.

The company started showing fact-checking labels to US viewers on its video platform YouTube in April in a bid to curb coronavirus misinformation, which exploded on social media as the pandemic intensified. 

Tech companies have been facing calls to police content more aggressively in recent years, after their hands-off approach allowed fake accounts and false claims to become rampant online.

YouTube has surfaced links to sources such as Encyclopedia Britannica and Wikipedia to address common hoaxes since 2018, but said in its April announcement that it would start directing efforts toward more fast-moving news cycles.

Shortly after that, it purged the wildly viral Plandemic video, which promoted a conspiracy theory about the pandemic to millions of viewers within just a few days.

Twitter and Facebook have also introduced fact-checking programs and warning labels for "manipulated media," although critics say the moves are too limited in scope.
