Aggregation Theory

Thompson names the idea connecting much of his analysis: before the internet, firms profited by controlling distribution and tying it to supply. Once distribution became free and transaction costs fell to near zero, the winners became companies that offer the best user experience, gather huge numbers of users, and then draw suppliers to them. He applies this pattern to Google, Facebook, Amazon, Netflix, Uber and Airbnb.

• Every consumer market can be split into suppliers, distributors, and consumers, and profits come from monopolizing or integrating these parts.
• Pre-internet distributors such as newspapers and publishers integrated backward into supply because controlling distribution gave them leverage.
• Free digital distribution and near-zero transaction costs let new firms integrate forward with users at enormous scale.
• User experience becomes the deciding factor, since more users attract more suppliers, which in turn improves the experience.
• Aggregators enjoy winner-take-all dynamics because their services improve as they serve more people.
• Thompson expects industries without obvious digital parts, like taxis and hotels, to be reshaped once a key function is digitized.

Thompson's prose is analytical and compact, built from definitions, chains of cause and effect, and paired examples. Retyping it trains precise business vocabulary, long sentences held together with colons and semicolons, and a habit of stating a framework before applying it.
