This document discusses celebrity endorsement, repositioning, and brand extension as marketing strategies. Celebrity endorsement involves using well-known people to promote products and raise awareness. It can build brand equity but risks damaging the celebrity or brand image if misaligned. Repositioning changes how a brand is perceived by modifying its key benefits. Successful repositioning requires analyzing current perceptions, developing a new strategy, and marketing changes. Brand extension leverages an existing brand name for new products, reducing costs but risking damage if the extension does not fit. Examples like Cadbury in India and Nike extending to different product categories are provided.
