Sid & Marty Krofft Television Productions, Inc. v. McDonald's Corp.
562 F.2d 1157 (9th Cir. 1977) - full text opinion
The Krofft brothers were contacted by a variety of advertisers hoping to capitalize on this popularity. Among them was the defendant Needham, Harper & Steers, Inc., which was trying to secure an advertising account with McDonald's. It 's proposal was to create an ad campaign featuring McDonaldland, filled with characters adapted from the Krofft's popular show.
Needham promised to pay the Kroffts, but later informed the brothers that the ad campaign had been canceled and that no money was forthcoming. The Kroffts promptly sued when the McDonaldland commercials began to air.
