Jake, my feeling is that all brands start out as single (or maybe more than one) products. Then if successful they expand into brands. So once you would have bought Nike shoes because they were good. Now you're supposed to buy Nike everything, though there's no evidence (that I know of) that Nike baseball caps are any better than anyone else's. Radio Times is still just a product. When they start marketing Radio Times trainers or butter, in hopes that readers will buy them because they like the magazine - that will be a brand.
