The U.S. Open is using several technology firms that range from startup Origin Digital to giant IBM to live stream more than 150 tennis matches online for this year's tournament. That's significantly more than last year, when only the men's final between Roger Federer and Andy Roddick was streamed, because rain postponed it to Monday when viewers would be at work. If last year's streaming garnered 300,000 views with little promotion, how much traffic will stampede onto USOpen.org this year?
