Japanese Media Groups Sue AI Search Engine Perplexity Over Alleged Copyright Infringement

Two of Japan's largest media groups are suing AI search engine Perplexity over alleged copyright infringement, joining a growing list of news publishers taking legal action against AI companies using their content.
