How would advertising be used to extend the life span of a product at each stage of the cycle?

Advertising can be strategically utilized at each stage of a product's life cycle to extend its longevity. During the introduction stage, it can create awareness and generate initial interest. In the growth stage, targeted campaigns can highlight unique benefits, encouraging wider adoption. For the maturity stage, advertisements can focus on brand loyalty and differentiation, while in the decline phase, rebranding or repositioning through nostalgic or innovative ads can revive interest and prolong the product's relevance.
