Global consumer perceptions of store brands have improved in recent years, gaining on national brands in key areas. A three-year study found that from 2010 to 2011, store brands were seen as being of higher quality, more innovative, and having better packaging than in previous years. Retailers have invested more in developing their store brands, launching specialty lines that enhance perceptions of quality and differentiation from national brands. National brands now face stronger competition from store brands and must work to emphasize their superiority in innovation and product quality.
