The U.S. Open also boasts a host of big sponsors.
"We've got JPMorgan Chase (JPM) - Get JPMorgan Chase & Co. Report , American Express (AXP) - Get American Express Company Report , Emirates Airlines, Mercedes-Benz and IBM (IBM) - Get International Business Machines Corporation Report ," said Lew Sherr, chief revenue officer of the United States Tennis Association, adding that the newest sponsor is food retailer Dean & DeLuca.
Sherr said the tennis sport is facing challenges in attracting millennials, similar to the issues in the golf industry. "We have invested heavily in youth participation," he said, noting that a can of tennis balls only costs $3.99.
