Sony Corp. of America v. Universal City Studios, Inc. (1984) and Kirtsaeng v. John Wiley & Sons, Inc. (2013) are the two landmark cases. 1. Sony (the “Betamax” case) • Core question: Did selling home video recorders that consumers used to copy broadcast TV constitute contributory copyright infringement? [1] • Ruling: 5-4, the Court said household “time-shifting” was fair use and Sony was not liable because the device was “capable of substantial non-infringing use.” [1] • Effect on first sale/rental: By assuring that VCRs could be lawfully sold, the decision let retailers buy tapes once and then rent them repeatedly under the first-sale doctrine, creating the video-rental industry. • Long-term impact: It legitimized consumer recording technologies, paving the way for DVRs, MP3 players, and later streaming-device innovation without immediate liability fears. [2] 2. Kirtsaeng • Core question: Could a U.S. publisher stop a student from reselling lawfully bought textbooks that were printed abroad on the ground that §109(a) first-sale rights applied only to copies made in the United States? [3] • Ruling: 6-3, the Court held that first-sale rights apply to any legally made copy regardless of manufacturing location; Kirtsaeng’s resale was lawful. [3] • Effect on first sale/rental: The decision removed geographic limits, confirming that stores could import legitimate foreign DVDs, books, or games and rent or resell them just like domestically produced copies. • Long-term impact: Publishers lost the ability to sustain international price discrimination; textbook and entertainment firms shifted toward digital distribution and access codes to regain control over secondary markets. [4] Together, the cases preserved robust first-sale rights that undergird secondary markets for physical media, enabling video rental shops and later used-media businesses to flourish.

The two cases were **Sony Corp. of America v. Universal City Studios, Inc.** (1984) and **Kirtsaeng v. John Wiley & Sons, Inc.** (2013) [1][2]. In **Sony**, the core question was whether home users’ recording of free over-the-air television on Betamax machines (“time-shifting”) was copyright infringement, and whether Sony could be secondarily liable for selling the VCR [1]. The Court ruled 5–4 for Sony, holding that private, noncommercial time-shifting was fair use and that a device with substantial noninfringing uses could lawfully be sold [1]. Although not a first-sale case in the narrowest sense, Sony protected the legality of VCR technology itself, which made prerecorded videocassettes a viable consumer product. That, combined with first sale, allowed stores to buy legitimate tapes and rent them out without needing separate permission from copyright owners. Long term, **Sony** helped create the home video market, fueling video rental chains and later influencing doctrine protecting multipurpose technologies [1]. In **Kirtsaeng**, the question was whether the Copyright Act’s first-sale doctrine applied to copies lawfully made abroad, specifically cheaper foreign editions of textbooks resold in the United States [2]. The Court ruled 6–3 that first sale does apply to lawfully made foreign-manufactured copies [2]. This clarified that once a copyright owner sells a lawful copy, its control over downstream distribution is generally exhausted, regardless of where the copy was manufactured [2][3]. That ruling strongly reinforced the legal foundation for rental and resale businesses by preventing copyright owners from using manufacturing location to block secondary markets. Long term, **Kirtsaeng** protected libraries, used-book sellers, and retailers dealing in imported copyrighted goods, while constraining publishers’ ability to segment global markets through copyright-based resale restrictions [2][3]. ## References 1.
