Kennedy, J., concurring
fair use test in § 107. The first factor (the purpose and character of use) itself concerns the definition of parody. The second factor (the nature of the copyrighted work) adds little to the first, since “parodies almost invariably copy publicly known, expressive works.” Ante, at 586. The third factor (the amount and substantiality of the portion used in relation to the whole) is likewise subsumed within the definition of parody. In determining whether an alleged parody has taken too much, the target of the parody is what gives content to the inquiry. Some parodies, by their nature, require substantial copying. See Elsmere Music, Inc. v. National Broadcasting Co., 623 F. 2d 252 (CA2 1980) (holding that “I Love Sodom” skit on “Saturday Night Live” is legitimate parody of the “I Love New York” campaign). Other parodies, like Lewis Carroll’s “You Are Old, Father William,” need only take parts of the original composition. The third factor does reinforce the principle that courts should not accord fair use protection to profiteers who do no more than add a few silly words to someone else’s song or place the characters from a familiar work in novel or eccentric poses. See, e. g., Walt Disney Productions v. Air Pirates, 581 F. 2d 751 (CA9 1978); DC Comics Inc. v. Unlimited Monkey Business, Inc., 598 F. Supp. 110 (ND Ga. 1984). But, as I believe the Court acknowledges, ante, at 588–589, it is by no means a test of mechanical application. In my view, it serves in effect to ensure compliance with the targeting requirement.
As to the fourth factor (the effect of the use on the market for the original), the Court acknowledges that it is legitimate for parody to suppress demand for the original by its critical effect. Ante, at 591–592. What it may not do is usurp demand by its substitutive effect. Ibid. It will be difficult, of course, for courts to determine whether harm to the market results from a parody’s critical or substitutive effects. But again, if we keep the definition of parody within appropriate bounds, this inquiry may be of little significance. If a work targets another for humorous or ironic effect, it is by defini-
