You may be familiar with the story of New Coke. To recap, in the mid-1980s, Coca-Cola reformulated its flagship soft drink in an attempt to better compete with Pepsi. The new drink, named New Coke, failed miserably. But Coca-Cola saved its business by rereleasing the original formulation of Coke under the name Coca-Cola Classic. That, in and of itself, is an excellent case study in business management. However, the more contemporary story is how Coca-Cola has changed its business plan so that no one drinknot even Cokecan heavily influence the company's success and failure. After years of diversification and acquisition, Coca-Cola currently offers more than 500 brands ranging from soft drinks to fruit juices to water. Additionally, it sells its products in over 200 nations.
