Simply defined, a brand portfolio is the collection of brands owned by a company. Often for big companies, more and more brands are created to reach more and more audiences. While targeting more audiences sounds like a great way to build and grow a company, too many brands can cause confusion about each individual brand’s role – and eventually the corporate identity as a whole. The problem many companies face is thinking more brands will make them more successful, however. they lack the architecture and the ability to manage a multiplicity of brands well.
