The document discusses the product life cycle of garments sold on online markets. It begins by defining what a product is and explaining product life cycle stages. It then details each stage of the product life cycle: introduction, growth, maturity, and decline. Marketing efforts differ at each stage. As an example, it examines the online fashion retailer ASOS, which has a short product life cycle due to constantly changing trends. It maintains growth by adding 1,000 new products per week and targeting customers aged 16-34. Understanding the product life cycle allows marketers to effectively promote, price, and distribute products throughout their lifespan.
