Aggregation Theory describes how platforms (i.e. aggregators) come to dominate the industries in which they compete in a systematic and predictable way. Aggregation Theory should serve as a guidebook for aspiring platform companies, a warning for industries predicated on controlling distribution, and a primer for regulators addressing the inevitable antitrust concerns that are the endgame of Aggregation Theory.
Aggregation Theory was first coined in this eponymously-titled 2015 article. That article followed on the heels of a series of posts about Airbnb, Netflix, and web publishing that, I realized, fit together into a broader framework that was applicable to a range of Internet-enabled companies. Over the ensuing two years I have significantly fleshed out the ideas in that original article, yet subsequent articles necessarily link to an article that marked the beginning of Aggregation Theory, not the current state.
