A MOD's major brands are your anchor stores

Each of the major MODs have some popular brands in their marketplace. CafePress has American Idol and Twilight Eclipse. Zazzle has Disney and Barbie. Spreadshirt has CNN and Nissan. Just from these examples, what might you surmise about the typical customer in each POD? One reasonable conclusion would be that CafePress attracts teenagers and young adults, Zazzle attracts children and “tweens”, and Spreadshirt attracts older adults.
The major brands serve the same purpose as the “anchor” stores in a traditional shopping mall. An anchor store is usually the largest store in a mall, and is usually located at one of the ends of a mall. Shoppers are more likely to visit a mall that has anchor stores that appeal to them. They begin by entering the anchor store at the end of the mall, but then they often walk further into the mall and visit other stores.
