I review the substantial precision electroweak and finetuning motivations for the Higgs boson(s) which carry the WW,ZZ couplings to have mass below the LEP limit for the SM and lightest MSSM Higgs boson. The manner in which the Next to Minimal Supersymmetric Model allows for a <100GeV Higgs boson with SM-like WW,ZZ coupling via dominance of h\to aa decays (where a is a CP-odd Higgs boson of the NMSSM) is summarized. The very substantial ability of hadron colliders to exclude or discover the light a is discussed. The challenges associated with detecting the h at a hadron collider are emphasized. More complex Higgs sectors that minimize finetuning and satisfy the precision data constraints naturally are summarized.
