The document discusses brand revival and decline. It provides examples of Ford reviving the Taurus brand and GM discontinuing the Oldsmobile brand. Brand decline can occur due to lack of innovation, strong competition, negative perceptions, and neglect by management. Guidelines for brand revitalization include differentiating the brand, investing in quality, assessing target markets, and addressing the original cause of decline. Simply lowering prices or adding extensions may not solve the underlying problems that led to decline. Reviving a brand is a long-term process that requires properly diagnosing issues and executing an effective strategy.
