Yesterday we told you about how United Airlines went from a $12 stock for a $0.01 in a single morning, when a reporter from the financial newsletter Income Securities Advisors found a six-year-old story about United's former bankruptcy (it entered protection in 2002, and exited in 2006), treated it like it was breaking news, and posted the item to Bloomberg News, which got picked up by Tribune Co.'s Florida Sun-Sentinel. It turns out, Income Securities was just performing a regular Google News search when it found the item, which was posted to the Sun-Sentinel's list of most-viewed stories, but without a 2002 date. Which means Google News, supposedly powered by a complex algorithm superior to human editing, erroneously pulled the story into its newsfeed and treated it as a brand new article, leading others to believe the story was fresh. Shareholders jumped on the news, selling off United stock, and driving the shareprice down rapidly before trading was frozen. Congrats, Brin & Page.
