In "Metropolitan Opera Ass'n v. Wagner-Nichols Recorder Corp.", the trial court described New York misappropriation law as standing for the "broader principle that property rights of commercial value are to be and will be protected from any form of commercial immorality"; that misappropriation law developed "to deal with business malpractices offensive to the ethics of [] society"; and that the doctrine is "broad and flexible." In that case, the defendant engaged in a "business malpractice offensive to the ethics of society": it copied and recorded the Met's opera broadcasts, which interfered with the Met's exclusive recording contract with Columbia Records. (At the time, the Copyright Act did not yet extend to sound recordings.) This was not a "hot news" case but rather an improper copying case. It shows the expansion of the "INS" doctrine beyond "hot news" to a more general misappropriation doctrine.
