Facebook owner Meta announced major changes to its policies on digitally created and altered media on Friday, ahead of U.S. elections poised to test its ability to police deceptive content generated by new artificial intelligence technologies.

The social media giant will start applying "Made with AI" labels in May to AI-generated videos, images and audio posted on its platforms, expanding a policy that previously addressed only a narrow slice of doctored videos, Vice President of Content Policy Monika Bickert said in a blog post.
