Sony is a venerable name in the world of consumer electronics. This is, after all, the company that invented the CD, the Walkman, the Blu-ray Disc, and has made a deep impression on the tech world and mainstream culture.
That's why when Sony screws up--something a company is apt to do every now and again while in business more than half a century--it's notable. Sometimes it's a singular event, other times it's a product with high expectations that ends up being a dud.
The latest mistake, the hacking of PlayStation Network customers' personal data, is a big one, though when put in the context of past events, it may not actually be the worst thing ever to befall Sony.
