A "Product Line" refers to a group of related products offered by a company. These products usually share similar characteristics, functions, or target markets. For example, a company like Apple may have a product line that includes various models of iPhones, each designed to cater to different customer needs and preferences. Companies often develop product lines to enhance brand recognition and streamline marketing efforts. By offering a range of products within a single line, businesses can attract a wider audience and encourage customers to explore additional options. This strategy can lead to increased sales and customer loyalty over time.
