A list of Amazon’s businesses and subsidiaries
Not very useful. Many of the listings have “Amazon” in the name so it’s obvious who owns them. Most of the rest are branded items, which isn’t the same as a “business” because I think most people know that retailers sell branded items, and besides, Amazon prominently identifies many of these, such as “Pinzon by Amazon”.  So really all that is left is maybe half a dozen items, like Zappos and Whole Foods.
