Network effects

The data and marketplace flywheel2000-present

Every searcher's queries improve results for the next searcher (a data network effect), and more searchers plus more advertisers deepen the auction's liquidity. The product and the marketplace each get better as the network grows, so value rises with the user base the leader already has.

• The cycle is get distribution... which drives volume of searches, more searches drives keyword bids, keyword bids drive up price in auctions, the price creates more revenue for Google, more revenue for Google means they can pay more for distribution. The virtuous cycle obviously goes on.

• David:The flywheel effect of liquidity in the marketplace of users and queries and advertisers... Once Google had that realization of oh, our business gets better the more users and advertisers we have, and thus we should be willing to spend basically anything to increase those two pools.

Liberty's media flywheel: Drive to Survive2017-present

The network makes itself inevitable1970s-present

Once Visa reached critical mass on both sides, no merchant could refuse to accept it and no consumer could afford to not carry it. The network's value to each new participant rises as the others join — and by the time you notice it's won, it's already won.

• Ben:Would you rather own a few percent of something that is the default global way that commerce is produced? Or would you rather own 100% of BankAmericard's?

Third-party marketplace: let rivals sell, take the cut2000-present

Amazon opened its platform to third-party sellers starting in 2000. By 2023 ~60% of units sold on Amazon are from third parties, who pay ~15% commission plus fulfillment fees. The marketplace adds selection Amazon cannot profitably stock itself, while Amazon captures the margin without the inventory risk.

Real-identity social graph — the unreplicable seed2004-present

Facebook seeded the real-identity social graph at Harvard in 2004 and expanded outward. Once your real friends, family, and professional contacts are in one network, no rival can offer you a better graph — they can offer you a blank one. This is the original network-economies moat: the value of Facebook to each user rises as their actual social network joins, and a competitor starts with zero of those relationships.

• David:The social graph — the actual graph of your real relationships — is the moat. Not the product. Not the UI. The data. Once your real friends are on Facebook, there is no migration. You can't take that graph with you.
