Groupon reported that it had a net loss in the fourth quarter Wednesday, a disappointing first result as a publicly traded company, reports Reuters. The company blamed the loss on higher overseas taxes. Analysts had actually expected a profit for the company, which is out "to prove to investors that it’s a real, money-making business and not just a fad," writes The Wall Street Journal. The results aren't a great sign for those in the "non-fad" camp.
