William Wrigley Jr. began selling soap in 1891 and offered free gum with purchases. The company established its first non-US factory in Canada and built its headquarters in Chicago in 1924. In 2007, Wrigley had $5.4 billion in revenue and $632 million in profits. However, Mars acquired Wrigley for $23 billion in 2008, making it the largest acquisition in the confectionary industry. Wrigley focuses on sustainability initiatives like recyclable packaging and uses renewable energy sources. Despite the acquisition, Wrigley's financial future remained strong with 15% revenue growth projected for 2007-2008.
