Why decades matter in IMC

Agencies are products of their founding moment. A shop founded in the early postwar period grew up alongside the modern advertising industry itself; one founded in the 1980s came up through the consolidation wave that built the holding companies; one founded in the 2010s has never known a world where digital, social, and performance media weren't already core to the brief. Founding decade isn't destiny, but it shapes house style and operating model in ways that persist for a long time.

Reading the decade view alongside the specialization view often surfaces patterns that neither view alone makes obvious — for instance, the rise of strategy-led independents in particular eras, or the shift in dominant craft from broadcast creative to digital craft over time. Use it as one lens among several.
