Well before the year 1900, baseball was already known as the American National Game. Once a simple pastime for boys, it evolved in the nineteenth century into a commercialized spectator amusement operated by promoters and played by professionals within a nationwide, monopolistic structure called Organized Baseball. The game's history reflects much of the concurrent history of the United States, and American interest in the game has grown exponentially since its beginnings. During the rise of the manufacture of board and card games in the mid-nineteenth century, it was natural that producers made games that mimicked the play of the game that virtually every boy and man loved. This practice continues up to the present time. One of the most realistic of baseball simulation games is Milton Bradley's Sandlot Slugger. The game's rather unique batting device is shaped like a player. This game was designed for Milton Bradley by Marvin Glass Associates, a famous Chicago toy design firm.
