From the beginning, Blockbuster was an immediate success -- and soon devised a model that would revolutionize the industry: With more than 8,000 VHS tapes in more than 6,500 titles, Cook's Blockbuster store was three times larger than its nearest competitor. Unlike other video chains that stored movies behind the counter, Blockbuster displayed titles on shelves. Cook kept his doors open later than traditional video stores. He used a computer system and scanner to track of tapes and ease checkouts. And in perhaps the most crucial move for future growth, Cook determined that Blockbuster would be a family-friendly destination, and he refused to stock adult films. Cook, realizing he had something powerful in his hands, decided to completely abandon the oil industry, renaming the company Blockbuster Entertainment and issuing a new ticker on Nasdaq.
