On 13 May 2002, Blockbuster, Inc., the leading US video rental chain, hit its highest stock price to date at almost $30 per share. Six years later, the price has fallen below $3 per share. The biggest reason for the decline? A Web site.

Not just any Web site, though. I'm talking about the Web site of a small startup named Netflix, which has now grown to have a market cap that is three times that of Blockbuster's. While Blockbuster is shutting down its stores and laying off employees, Netflix is experiencing year-after-year profits.
