E-books are a rapidly growing industry, and companies such as Apple(NASDAQ:AAPL) and Amazon.com(NASDAQ:AMZN) are looking to cash in on it. Times have been tough lately for Apple, however, and not just because of its low stock price.

Last April, the Department of Justice filed a lawsuit against Steve Jobs' brainchild, as well as five of the United States' largest publishers. The suit claimed that these companies had been involved in price fixing for many of their e-book products.  

Even after a year, the case has yet to be resolved. However, tensions are building between Apple and Amazon over e-books, and one of Apple's chief executives has been called to testify in the case. Could this case be detrimental, or is it not that big of a deal? Fool contributor Caroline Bennett has more in the following video.
