Aggregation Theory (07.21.15)

Author: Ben Thompson in Stratechery URL: https://stratechery.com/2015/aggregation-theory/ One-line: The internet made distribution and transaction costs zero, flipping the value chain so that whoever owns the user relationship — not whoever controls distribution — wins. Aggregation Theory

Key claims

• The value chain for any consumer market splits into three parts: suppliers, distributors, and consumers/users. The best way to make outsize profits is to gain a horizontal monopoly in one part, or to integrate two parts for a competitive advantage in a vertical solution. Pre-internet, the latter depended on controlling distribution.
• The internet turned this on its head: it made distribution of digital goods free (neutralizing the distributor’s old advantage), and made transaction costs zero, making it viable for a distributor to integrate forward with end users at scale.
• Order matters: Google pioneered the model by modularizing content providers. Content has always been monetized by proxy — newspapers, CDs, cable TV — and “the shift to digital has exposed these proxies for the rent-collection mechanisms they are.”
• All the examples share strong winner-take-all effects: the services become better the more users they serve, and they can serve every consumer on earth. ==This, above all else, is why consumer technology companies are so highly valued both in the public and private markets.==

• The fundamental disruption of the Internet has been to turn this dynamic on its head. First, the Internet has made distribution (of digital goods) free, neutralizing the advantage that pre-Internet distributors leveraged to integrate with suppliers. Secondly, the Internet has made transaction costs zero, making it viable for a distributor to integrate forward with end users/consumers at scale.
• The value chain for any given consumer market is divided into three parts: suppliers, distributors, and consumers/users. The best way to make outsize profits in any of these markets is to either gain a horizontal monopoly in one of the three parts or to integrate two of the parts such that you have a competitive advantage in delivering a vertical solution. In the pre-Internet era the latter depended on controlling distribution.
• It’s interesting to consider the order of these examples: the pioneer of this model was Google which modularized content providers. It’s easy to see why this is the case: content has always been monetized by proxy, whether it be paying for newspapers (or advertising space in those newspapers), paying for CDs, or paying for cable TV. The shift to digital has exposed these proxies for the rent-collection mechanisms they are.
• What is important to note is that in all of these examples there are strong winner-take-all effects. All of the examples I listed are not only capable of serving all consumers/users, but they also become better services the more consumers/users they serve — and they are all capable of serving every consumer/user on earth. ==This, above all else, is why consumer technology companies are so highly valued both in the public and private markets.==
