The New York Times and the Chicago Tribune have both initiated legal proceedings against the AI startup Perplexity, alleging copyright infringement for the unauthorized use and verbatim copying of their content. The New York Times asserts that Perplexity has lifted its work without permission, while the Chicago Tribune further claims that the AI company misused content and violated its copyright. This wave of lawsuits highlights an escalating battle over intellectual property rights in the age of artificial intelligence, with multiple media organizations joining forces against Perplexity for its alleged practices. In addition to the U.S. lawsuits, international media entities are also voicing similar concerns, marking a significant moment in the ongoing struggle for copyright enforcement in the digital era.
