The Betamax Case
Sony Corp. of America v. Universal City Studios, 464 U.S. 417 (1984)
The Supreme Court’s ruling in Sony v. Universal Studios (aka the Betamax case) is a landmark copyright precedent that has sheltered a wide array of technology innovators from lawsuits at the hands of the entertainment industries. In 1984, the Court held that a company — in this instance, a VCR manufacturer — was not liable for creating a technology that some customers may use for copyright infringing purposes, so long as the technology is capable of substantial non-infringing uses. In other words, where a technology has many uses, the public cannot be denied the lawful uses just because some (or many or most) may use the product to infringe copyrights.
