Google (NASDAQ:) is updating its political content policy to include a new mandate that all verified election advertisers must disclose uses of artificial intelligence (AI) in campaign content.

On Sept. 6, the tech giant said the disclosures are required where there is “synthetic content that inauthentically depicts real or realistic-looking people or events.” Additionally, it said these notices must be “clear and conspicuous” in places where users will notice them.
