"Petitioners manufacture and sell home video tape recorders. Respondents own the copyrights on some of the television programs that are broadcast on the public airwaves. Some members of the general public use video tape recorders sold by petitioners to record some of these broadcasts, as well as a large number of other broadcasts. The question presented is whether the sale of petitioners’ copying equipment to the general public violates any of the rights conferred upon respondents by the Copyright Act. Respondents alleged that some individuals had used Betamax video tape recorders to record some of respondents’ copyrighted works which had been exhibited on commercially sponsored television and contended that these individuals had thereby infringed respondents’ copyrights. Respondents further maintained that petitioners were liable for the copyright infringement allegedly committed by Betamax consumers because of petitioners’ marketing of the Betamax VTR’s. The District Court denied respondents all the relief they sought and entered judgment for petitioners. The United States Court of Appeals for the Ninth Circuit reversed the District Court’s judgment on respondent’s copyright claim, holding petitioners liable for contributory infringement. We now reverse."
