The Polo Sport line was introduced in 1993. In 1997, the company went public on the New York Stock Exchange. By now, the company was structured to operate as an umbrella for its brands and other ventures and would be named the Ralph Lauren Corporation by the early-21st century. It was originally named Polo Ralph Lauren Corporation, but in subsequent years the Polo in the name was dropped to reflect the company’s presence in other concepts beyond the Polo line. The original Polo line remained as the flagship brand of the company. Ralph Lauren Corporation also manages several other brands, including Ralph Lauren Black Label, Ralph Lauren Purple Label, Ralph Lauren Blue Label, Lauren Ralph Lauren, Club Monaco, and Chaps.
