Maybe there‘s something to all that talk about America catching the soccer bug. The recent success of the United States at the World Cup hasn‘t just meant huge TV ratings, but also a big spike in Team USA merchandise sales. At e-commerce sports retailer Fanatics, Jack Boyle, president of merchandising, said his firm has had to re-order additional merchandise from supplier Nike three times already. "The white jerseys Team USA is wearing have been the No. 1 selling jersey on all of Fanatics," Boyle told CNBC. The Fanatics website is seeing a 50 percent increase in soccer merchandise orders on Team USA game days and the day following. Just how hot is soccer? More Team USA merchandise has been sold on Fanatics.com in the first two weeks of this year‘s World Cup than during the entire 2010 calendar year. And in the last seven days, Team USA gear has been purchased by customers in all 50 states and more than 15 countries.
