  • This source(Bibliography-only — uncited in body; contamination.)

• Economies of Scale
  • In online services, a streaming platform's fixed cost of licensing or producing content is amortized across millions of subscribers — the larger the subscriber base, the lower the cost per viewer for a given content library, reinforcing the leader-firm economics that Katz and Shapiro (1985) analyzed as the interaction of network externalities with scale-driven cost advantages in compatibility-sensitive markets.

    This sourceFormal model of demand-side network externalities: value to each user rises with the installed base, with implications for compatibility, standards competition, and winner-take-most concentration; NOTE: this is a demand-side network-effects paper; the prose's phrase 'scale-driven cost advantages' is contextual framing rather than the paper's own analysis, but the network-externality / leader-firm attribution is accurate.

• Increasing Returns
  • … foregrounds the supply-side channel where Smith (1776) located rising productivity in the division of labor, and learning_curve_effects foregrounds the experience channel that Wright (1936) first quantified in airplane manufacturing — all three are the same four-role pattern under different reinforcement channels.
• Interface
  • Listed in the references but not attached to a specific claim.
• Network Effect
  • Michael Katz and Carl Shapiro extended this foundation through their mid-1980s work: "Network Externalities, Competition, and Compatibility" (1985)
• Platform Design
  • A common failure is exploiting ecosystem lock-in until antitrust intervention or competitive disruption forces change
• Specialization
  • Listed in the references but not attached to a specific claim.
• Standardization
  • This reframes standard wars, format battles, and adoption struggles as what they are: coordination contests where the prize is being the shared norm, not being the best design — which is why standards battles are won by tipping, bandwagons, and installed base as much as by technical merit, and why the loser of such a battle can have the better technology (Betamax, for the canonical example) and still lose.

    This sourceEstablishes that standards battles turn on installed base and network effects, so a technically superior option can lose.

• Strategic Complementarity
  • Technology adoption: every additional user of a platform raises the value of joining (telephone, fax, social networks); the network externality is complementarity at the user-choice layer.

    This sourceFoundational analysis of network externalities, where each additional adopter raises the value of joining — a canonical instance of strategic complementarity at the user-choice layer.

• Substitutability
  • Listed in the references but not attached to a specific claim.

Verification

Does it exist? Not checked yet. This entry carries no identifier to resolve. It was extracted from the citation as written in the article, normalized, and deduplicated against the rest of the registry.

Does it back the claim? Not recorded. Neither this nor any other of the 11 citations of this work carries a recorded support check.

Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
