Title: Theoretical Ideas About and Experimental Probes of Light Higgs Bosons\\
Abstract: I will repeat the talk I gave recently at the BaBar Meeting at SLAC in which I outline reasons why, and models in which, we might expect to have light Higgs bosons that have so far escaped detection. In particular, I will review the Next-to-Minimal Supersymmetric Model in which there is a 100 GeV Higgs boson that decays primarily via h->aa where m_a<2m_b. The importance of running BaBar on the \Upsilon(3S) resonance to probe this scenario is stressed at the end. Experimental issues at the LHC will also be discussed.
