In 1965, Riley exhibited in the Museum of Modern Art in New York City show, "The Responsive Eye" (created by curator William C. Seitz); the exhibition which first drew worldwide attention to her work and the Op Art movement. Her painting "Current", 1964, was reproduced on the cover of the show's catalogue. Riley became increasingly disillusioned, however, with the exploitation of her art for commercial purposes, discovering that in the USA there was no copyright protection for artists. The first US copyright legislation was eventually passed, following an independent initiative by New York artists, in 1967.
