History

Historical Context

After the Recording Industry Association of America sued Napster in December 1999, a July 2000 injunction forced the service to block copyrighted songs, and the Ninth Circuit later affirmed Napster’s liability for contributory infringement, leading to its 2001 shutdown after peaking at 26.4 million users. Those precedents—followed by Grokster (2005) and LimeWire (2010)—now shape the RIAA’s suit against Anthropic seeking damages per work.
