YouTube will fight back against hugely popular conspiracy theory videos flooding its website, including those suggesting the moon landing was faked, by showing viewers facts on the topic.

“Starting today, users will begin seeing information from third parties, including Wikipedia and Encyclopædia Britannica, alongside videos on a small number of well-established historical and scientific topics that have often been subject to misinformation, like the moon landing and the Oklahoma City Bombing,” YouTube’s chief product officer Neal Mohan and chief business officer Robert Kyncl said.

It also unveiled plans to challenge hoax videos that frequently appear during breaking news events, by showing viewers news articles instead.

In the wake of recent failures to stop conspiracy theories surrounding terrorist attacks being promoted on the platform, the streaming website will present users with warnings that videos about breaking news may be unreliable.

Algorithms will spot when trusted publishers break stories and place a preview of the article in the search results with the option read the full version as a story develops.
