How fo industry profits change as a product moves through the four stages of its life cycle?

As a product progresses through its life cycle—introduction, growth, maturity, and decline—industry profits typically follow a specific pattern. In the introduction stage, profits are often low or negative due to high development and marketing costs. During the growth stage, profits increase significantly as sales rise and economies of scale are realized. In the maturity stage, profits may stabilize or decline due to market saturation and increased competition, while in the decline stage, profits generally decrease as consumer interest wanes and sales diminish.
