Long before on-demand streaming—and even before DVR recording—Gen Xers and some Millennials will remember using a VCR to record TV shows for later viewing. Two competing, noncompatible tape formats dominated the market: VHS and Beta. While the backstory of the format wars is interesting, all that matters here is that Sony created and backed the Beta videotape format.
In the early 1980s, Sony—the manufacturer of the Betamax® VCR—was sued by the television industry for copyright infringement based on consumers’ use of Sony VCRs to record network television programs. The case ultimately reached the U.S. Supreme Court, which held that Sony was not liable for contributory copyright infringement arising from consumers’ use of the Sony Betamax® to “time-shift” recorded programs.
