Armstrong guarded the use of his name, image, and famous quote. When it was launched in 1981, MTV wanted to use his quote in its station identification, with the American flag replaced with the MTV logo, but he refused the use of his voice and likeness. He sued Hallmark Cards in 1994, when they used his name, and a recording of the "one small step" quote, in a Christmas ornament without his permission. The lawsuit was settled out of court for an undisclosed sum, which Armstrong donated to Purdue.
