  In this talk, I shall address two key issues related to electroweak symmetry
breaking. First, how fine-tuned different models are that trigger this
phenomenon? Second, even if a light Higgs boson exists, does it have to be
necessarily elementary? After a brief introduction, I shall first review the
fine-tuning aspects of the MSSM, NMSSM, generalized NMSSM and GMSB scenarios. I
shall then compare and contrast the little Higgs, composite Higgs and the
Higgsless models. Finally, I shall summarize by giving a broad overview on
where we stand at the end of 2011.
