News Corp Units Sue Perplexity Over Copyright Use

News Corp subsidiaries, Dow Jones and the New York Post, have filed a copyright infringement lawsuit against AI startup Perplexity, alleging the unauthorized use of their content to train its AI system. The lawsuit claims Perplexity copies and uses copyrighted material on a large scale, diverting traffic and revenue from the publishers. Despite a cease-and-desist letter sent in July, Perplexity reportedly did not respond, prompting the legal action. News Corp argues that Perplexity's AI-generated summaries allow users to bypass publishers' websites, thus undermining the revenue model for journalism. This legal battle reflects broader tensions between media companies and AI firms over content usage rights. The lawsuit follows similar actions by other publishers, highlighting the urgent need for clear guidelines on AI's use of copyrighted content.
