In the modern era, the concept of branding has expanded to include deployment by a manager of the marketing and communication techniques and tools that help to distinguish a company or products from competitors, aiming to create a lasting impression in the minds of customers. The key components that form a brand's toolbox include a brand's identity, personality, product design, brand communication (such as by logos and trademarks), brand awareness, brand loyalty, and various branding (brand management) strategies. Many companies believe that there is often little to differentiate between several types of products in the 21st century, hence branding is among a few remaining forms of product differentiation.
