ABC Sued for $50 Million Over Home Video Show: A writer who says ABC stole his idea when it created “America’s Funniest Home Videos” filed a $50-million suit Wednesday in Superior Court, claiming that he was defrauded by the ABC network, Westinghouse Broadcasting Co. and others. The suit by Joseph Kaufman said he developed the idea of using amateur home videotape on television and had an oral contract to try out the concept on the syndicated one-hour “Wil Shriner Show” in November, 1987. ABC declined comment on the suit. (Filed Feb. 21; Case No. C752902)
