In this talk I give a brief overview of the idea, focusing mainly on the littlest Higgs model, and present a sampling of the electroweak precision constraints.7 pages, Talk given at the XXXVIII Rencontres de Moriond on Electroweak Interactions and Unified Theories, Les Arcs France, March 15-22, 2003High Energy Physics - Phenomenologytext
