Nintendo of America, Inc. vs. Blockbuster LLC was a 1989 legal case related to the copyright of video games, where Blockbuster agreed to stop photocopying game instruction manuals for Nintendo. Blockbuster publicly accused Nintendo of starting the lawsuit after being excluded from the Computer Software Rental Amendments Act, which limited the rental of computer software but allowed the rental of Nintendo's game cartridges. Nintendo responded that they were enforcing their copyright as an essential foundation of the video game industry.
