"According to US Copyright Law, protected works may be excerpted under "Fair Use" for "use in a parody of some of the content of the work parodied;". Many factors are to be considered, including how much of the copyrighted work is used, and "The effect of the use upon the potential market for, or value of, the copyrighted work".
Courts have unanimously ruled that parodies juxtaposing copyrighted content with a contrasting idea are considered to be valid examples of “Fair Use” under the doctrine. A substantial element for consideration is the notion of whether or not the resultant parody is “Transformative” of the original work.
So I present these transformed excerpts of “Law and Order - Jeff Goldblum Unit”, totaling less than .1% of the series, transformed by the repeated insertion of the image of jeff goldblum. In doing so, we have created, transformatively, a study in the art of the Television Title Sequence. The viewer is compelled to consider the title sequence that they have taken for granted so many times. The work is noncommercial, and uses too little of the original to seriously affect the marketability of the copyrighted works. As a matter of fact, if one were to see this transformation, without having seen the original works parodied, I submit that it would only increase their desire to commercially view the protected works.
Therefore, As per US Copyright Law, Relevant Case Decisions, and in particular Leibovitz v. Paramount Pictures Corp., 137 F.3d 109 (2d Cir. N.Y. 1998), this parody is fair use, it is allowed to be on youtube, and you really shouldn’t sue me.”
