Feature: How AT&T conquered the 20th century
It was January 1982. Despite a nasty recession, the personal computer revolution was in full swing. The Apple II had been on the market for five years. IBM launched its PC in 1981, and Compaq released its fully IBM compatible Portable model shortly thereafter.
Context & Ripple Effects
Ars Technica anchors its AT&T retrospective at January 1982, a deliberate counterpoint: while AT&T had spent the century conquering telecommunications as a vertically integrated monopoly, the personal computer industry it contrasts against was barely five years old — the Apple II's 1977 debut had seeded it, IBM entered with its PC in 1981, and Compaq quickly shipped a fully IBM-compatible Portable.
That framing is the analytical point of the piece: the same month finds one industry still organized around a single dominant institution and another already organized around an open compatibility standard that outsiders could clone. Prior corpus coverage has mostly told the PC side of that story; this feature supplies the incumbent-monopoly half.
First-order effects
- Readers get a unified account of how AT&T built and held 20th-century telecom dominance, positioned explicitly against the IBM-anchored PC ecosystem where Compaq's compatible Portable proved the standard could be copied rather than owned.
Second-order effects
- The comparison hands analysts a template for judging dominant tech firms: AT&T's model of controlling the whole network is set beside a market where IBM's own standard empowered rivals like Compaq, showing how quickly control of a format can leak to cloners.
Third-order effects
- If the pattern holds, the structural lesson is that institutions which conquer an industry by owning the infrastructure eventually meet either regulators or open standards — and the PC industry's clone-driven growth suggests the latter erodes dominance faster than any single competitor could.
The trend: Vertically integrated 20th-century network monopolies like AT&T are giving way to computing industries organized around open standards that invite competition by design.
