Copyright law works with the distinction between 'public' and 'private' whereas CreativeCommons introduced the distinction 'commercial' and 'non-commercial'. But since the beginning of CC in 2001, it has been unclear what these terms mean. Now, CC published a study that tries to come up with a common definition of the term, based on user feed-back. This will be used when it comes to developing the new version of the license (v.4.0), a multi-year process to be started in 2010.
Study findingsCreative Commons noncommercial licenses include a definition of commercial use, which precludes use of rights granted for commercial purposes:
… in any manner that is primarily intended for or directed toward commercial advantage or private monetary compensation.The majority of respondents (87% of creators, 85% of users) replied that the definition was “essentially the same as” (43% of creators, 42% of users) or “different from but still compatible with” (44% of creators, 43% of users) theirs. Only 7% of creators and 11% of users replied that the term was “different from and incompatible with” their definition; 6% or creators and 4% of users replied “don’t know/not sure.” 74% and 77% of creators and users respectively think others share their definition and only 13% of creators and 11% of users wanted to change their definition after completing the questionnaire.
