Anti-Monopoly, a board game created by Ralph Anspach, once found success as an antiestablishment alternative to Monopoly. Like Monopoly, Anti-Monopoly was a square board game with spaces representing conglomerates. The game rewarded breaking up monopolies, not building them. The game gained national press attention, but Parker Brothers, the company that made Monopoly, sued Anspach for trademark infringement. The company won, and all copies of Anti-Monopoly were destroyed. Anspach won a settlement from the company and regained full use of the Anti-Monopoly name. The game is now produced by San Francisco-based University Games.
