The 2006 peak in sales will be considered as THE MATURITY STAGE OF THE PRODUCT.
The life cycle of a product is divided into four different stages, which are introduction, growth, maturity and decline. The introduction stage refers to the time period when the product was newly introduced into the market, the growth period refers to the establishment of the product in the market while the maturity stage refers to the time when the product reaches its highest sales ever in the market. After this, the sales of the product decline in the market.
