On 17 September 2024, the Assembly Bill requiring electoral advertisements using AI-generated or substantially altered content to feature a disclosure that the material has been altered (AB 2355) was signed by the Governor of California. The Bill mandates that political ads containing AI-generated or substantially altered content include a clear disclosure indicating the use of AI. The Bill also sets out sanctions and enforcement by the Fair Political Practices Commission, and provides a definition for artificial intelligence. It also specifies the conditions for under which media is considered to be generated or substantially altered by AI. Aside from AI-generated political advertisements, the Bill also outlines disclosure requirements for political advertisements more generally, depending on the medium (radio, video, print, or digital). As a normal legislative measure, the Bill enters into effect on 1 January 2025.
