Raljon was the original place name of the campus of Northwest Stadium, home of the Washington Commanders. Former team owner Jack Kent Cooke (whose full name originally graced the stadium) derived the name from the names of his sons, Ralph and John. Introduced in 1997, the name enjoyed almost no currency beyond the team (then known as the Redskins), NFL press releases, television and radio partners, and the U.S. Postal Service, which granted Cooke's request that the area be officially recognized, which applied specifically to the stadium campus's extended 20785-4534 ZIP+4 Code.[18]Tony Kornheiser, in a column criticizing the name, wrote, "Lucky for us, Cooke didn't name his kids Peter and Ennis."[19]Daniel Snyder phased out the requirement to dateline of stadium events originating in Raljon before the 1999 preseason, and quietly phased out the placename soon after his purchase of the team.[18]
