Brand extensions allow companies to leverage existing brand equity when introducing new products. There are two main types: line extensions which target new segments within an existing product category, and category extensions which enter a new product category. Brand extensions provide several advantages for companies, including facilitating new product acceptance and reducing risks and costs. However, extensions also carry disadvantages like potential consumer confusion and dilution of the parent brand's image if not executed properly. When evaluating potential extensions, consumers assess how well attributes and benefits associated with the parent brand transfer to the new product category based on their existing knowledge of the brand.
