Seed 1.6 vs Kimi K2

The 1984 Supreme Court’s Sony Corp. of America v. Universal City Studios, Inc. anchored the first sale doctrine’s role in the video rental economy [1]. The case centered on the Sony Betamax home recording device, with MCA/Universal chief Lew Wasserman infamously labeling it the “Boston Strangler” for its perceived threat to film revenues [1]. The ruling upheld consumers’ right to resell or rent legally acquired media, clearing the way for the booming video rental industry by validating first sale’s application to home-recorded content. In 2013, the doctrine expanded via Kirtsaeng v. John Wiley & Sons, where Thai student Supap Kirtsaeng won a 6-3 decision that extended first sale protection to foreign-manufactured textbooks he resold in the U.S. [2]. This reinforced resale market viability for educational materials. The Massachusetts-based digital resale startup ReDigi was sued by Capitol Records over its digital music resale platform [3]. Judge Richard J. Sullivan denied Capitol’s preliminary injunction request, ruling ReDigi’s model—transferring original digital files and deleting the seller’s copy—did not conclusively violate copyright law, though he acknowledged lingering uncertainties about first sale’s digital-era scope [3]. This chain of rulings shaped cross-media resale markets, balancing copyright holders’ interests with consumer rights to redistribute legally obtained goods. ## References [1] Sony Corp. of America v.

The "first sale" doctrine's modern contours emerged from *Sony Corp. v. Universal City Studios* (1984), which legalized the Betamax VCR [1]. MPAA president Jack Valenti famously likened the device to the "Boston Strangler" [2]. This precedent enabled physical media rentals by affirming consumers' resale rights. The doctrine extended internationally in *Kirtsaeng v. John Wiley & Sons, Inc.* (2013), where Supap Kirtsaeng, a Thai student, legally purchased textbooks abroad and resold them in the U.S. [3]. The Supreme Court ruled 6-3 that first sale applies to lawful copies manufactured overseas, protecting his resale rights [4]. This principle faces challenges in digital markets. Massachusetts-based startup ReDigi created a platform for reselling digital music files. Capitol Records sued in 2013, arguing that digital transfers create unauthorized reproductions [5]. U.S. District Judge Richard Sullivan denied Capitol's request for a preliminary injunction, reasoning that ReDigi's technology, which transmitted files without creating additional copies, potentially complied with copyright law [6]. However, he later ruled the service infringed reproduction rights, distinguishing digital from physical transfer [7]. ## References [1] Sony Corp. v. Universal City Studios, 464 U.S. 417 (1984).
