It would be of no significance under our statute that Tiffanys Movie Theater is not a competitor of, nor likely to be confused with Tiffanys Jewelry. The harm that [the New York dilution statute] is designed to prevent is the gradual whittling away of a firms distinctive trademark or name. It is not difficult to imagine the possible effect which the proliferation of various noncompetitive businesses utilizing the name Tiffanys would have upon the publics association of the name Tiffanys solely with fine jewelry. The ultimate effect has been appropriately termed dilution.
