As Chicago wages its battle to host the 2016 Olympics, it also finds itself scrapping over a valuable piece of cyberspace: the domain name of chicago2016.com. The bid team along with the U.S. Olympic Committee are trying to wrest that online address from Stephen Frayne Jr., a 29-year-old MBA student. Frayne snagged it in 2004, about two years before the bid was launched. An engineer who is studying entrepreneurship at Northwestern University's J.L. Kellogg School of Management, Frayne in recent years has laid claim to 40 online addresses that combine a city name and year, including tokyo2016.com. Chicago, which uses chicago2016.org as its official web site, is seeking to win control of chicago2016.com through a complaint filed with an international arbitration organization. A decision could come as soon as Monday. Many Web users automatically type dot.com when searching for sites.
