"California Assembly Bills 1792 & 1793" were commonly called the "ultraviolent video games bills" or simply "video game ban" bills. Bill 1792 banned the sales of such video games while Bill 1793 required signs explaining the regulations on said games to be placed where such were sold. Both bills were passed by the Assembly and signed by Governor Arnold Schwarzenegger into law (AB 1179) on October 7, 2005.
