At least one company benefited from Olympics fans in the United States who tried to circumvent NBC’s television coverage during the London Games. AnchorFree, the Mountain View, Calif.-based startup released data to Reuters on Monday showing a major bump in users who installed a product that gives U.S. users an anonymous IP address in the United Kingdom. Presumably the people who signed up for the product, called ExpatShield, used it to watch BBC’s online streams of the Olympics.
