Abstract:  A fundamental conflict between digital participatory culture represented by “user generated content” and the modern copyright regime has been widely acknowledged. However, a comprehensive analysis of the following three aspects, namely, recent legislative initiatives and legal cases in the North American jurisprudence regarding the use of copyrighted works, new marketing strategies and profitmaking modes achieved by moderately relaxing copyright protection in the copyright industry, and the quasicopyright norms spontaneously established by participatory culture practitioners, reveals that there exists a principled consensus of the use of copyrighted work. It provides a new perspective and dimension in creating a congenial copyright environment for the orderly blossoming of participatory culture.
