Facebook (Meta) Network Effects Case Study

Facebook's rise is a textbook case of direct network effects. The more friends and family on the platform, the more compelling it became. As Facebook's user base swelled into the billions, it achieved a near-monopoly on personal social networking (Harnessing the Power of Network Effects for Product Success - Beyond the Backlog). Users are essentially "locked in" because their social graph (photos, contacts, groups) lives on Facebook: there's no equivalent network where all those same connections exist (Harnessing the Power of Network Effects for Product Success - Beyond the Backlog).

This scale also let Facebook layer on new services (Marketplace, Instagram integration, etc.) to further entrench users. A new social platform faces an uphill battle because it's not enough to build a better app; one would have to convince entire social circles to movem an unlikely prospect given Facebook's incumbency advantage (Why did Google+ fail? - Business School).

Twitter (now X) likewise benefits from network effects (though on a smaller scale), where the presence of celebrities, newsmakers, and one's interests all in one network keeps users coming back (Harnessing the Power of Network Effects for Product Success - Beyond the Backlog). These social platforms demonstrate how network effects can create winner-take-all outcomes: once Facebook "won" the social networking race, it won it big, capturing the lion's share of users in its category (What Are Network Effects? | HBS Online).
