With the discoveries at the Large Hadron Collider (LHC) at Cern as well as the nobel price this year much attention is payed to Higgs physics, 
responsible to generate the masses of the elementary particles. In this talk possible extensions of the Higgs sector are considered - which may 
be realized in Nature. The focus will lie on the general two-Higgs doublet model and sypersymmetric extensions.
