Branded House vs. House of Brands

Hey everyone,
To continue our discussion on Branded House versus House of Brands, here's something to consider: Is it possible that some industries move between House of Brands and Branded House?
In the case of Pharmaceutical companies, let's take Pfizer as an example. Pfizer, as we all know, sells many different drugs. Since Pfizer sells these drugs under different names (i.e. Zyrtec and Lipitor etc.), it would be considered a House of Brands. However, when something goes wrong, such as one of the drugs is proven to be harmful, consumers blame Pfizer instead of the individual drug's department. In this scenario, the consumers change the brand architecture from being a House of Brands to to a Branded House. Just my observation that some industries are specifically set on one type of architecture and others tend to be a little bit of both depending on the situation.
