Why do ad expenditures remain high in the growth stage of the PLC?

During the growth stage of the Product Life Cycle (PLC), ad expenditures remain high to capitalize on increasing market demand and to differentiate the product from competitors. Companies aim to build brand loyalty and awareness while expanding market share, often leading to aggressive advertising strategies. Additionally, as more consumers become aware of the product, consistent advertising helps maintain momentum and encourages repeat purchases. This investment in marketing is crucial for sustaining growth and maximizing profitability in a competitive landscape.
