CNN Sues AI Firm Perplexity, Alleging It Engaged in ‘Massive Copyright Infringement’

CNN sues Perplexity alleging ‘massive’ copyright infringement - SiliconANGLE

CNN has sued Perplexity AI for copyright infringement, alleging the company continued rewriting CNN's reporting without authorization after failed licensing negotiations and a formal cease-and-desist. The case signals that failed licensing talks are now converting directly into litigation, raising the legal risk for any AI product relying on unlicensed web content and likely accelerating pressure on foundation model and RAG vendors to formalize content agreements.
