There are three main types of brand architecture: 1) Monolithic system where the company name is placed on all products. This reduces advertising costs but if one product fails, it negatively impacts the whole brand. 2) Endorsed system where sub-brands are verbally or visually connected to the parent brand and benefit from its credibility. 3) Freestanding system where each brand operates independently based on its target market. The relationship between brands on this spectrum ranges from closely integrated to independent.
