An abbreviation with multiple lives: in business and government, P3 stands for public-private partnership — a model where public infrastructure or services are funded and operated through collaboration between government and private companies. In computing history, P3 was shorthand for the Intel Pentium III processor, a milestone chip of the late 1990s. Context determines which meaning you're dealing with, but the business/policy sense dominates in contemporary usage.

Origin: P3 as public-private partnership became widely used in infrastructure policy discussions from the 1990s onward; P3 as Pentium III was Intel's own product shorthand from 1999. Editorial expansion authored on Slangora.
