Leonard, Sean. "Celebrating Two Decades of Unlawful Progress: Fan Distribution, Proselytization Commons, and the Explosive Growth of Japanese Animation." UCLA Entertainment Law Review, Spring 2005
Leonard's paper on American fans' use and distribution of anime goes into great depth on the legal issues raised, and often ignored, in regards to copyrighted works. The original Japanese copyright holders spurred on American fan-imports and fansubs by "abandoning" the market early on; in this way it was law-breaking American fans, clubs and conventions that created almost single-handedly what is now a visible and profitable market for the Japanese owners and the American licensors. Currently, though the Japanese owners do finally play in the American marketplace, they are nearly as willfully ignorant (in practice) of fan infringement than they were when America was still written off as an impossible market. But while first this ignorance was a result of their not thinking any American infringement could possibly hinder them financially, reasons for this now include the historical and continued support and "free publicity" for anime that American fans would not be so willing to embrace legitimately had it not gained buzz from prior illegal distribution among fan networks. Yet Leonard outlines all of the various ways that obtaining, translating, distributing and showing fansubs break any number of American and international copyright laws. Though fans often cite fair use as a defense for their actions (though a case has never been brought to court), Leonard dismisses all of the potential factors that would constitute fair use save for the "purpose and character" in the commerciality of fansubbing; in this case, fans often do their work for no profit and as a courtesy to fellow fans. In every other sense, their use is wholly unfair.
Here we see the rough legal guidelines that both Japanese and American anime copyright holders tend to adhere to when dealing with fans. In general, fan's use of anime is forgiven and often ignored, unless it exists in direct competition with legitimate localized releases. Anime Music Videos (not mentioned by Leonard) are another, altogether less potentially dangerous (than importing and fansubbing) form of "free advertising" for anime and of strengthening the fan networks that built and maintain the American anime audience. Again, Japanese copyright holders are shown to display a willful ignorance of American fans use for the most part.
