Abstract
The next--to--leading order predictions for the branching ratio BR(B -> X_s gamma) are given in a generalized class of two Higgs doublets models. Included are the recently calculated leading QED corrections. It is shown that the high accuracy of the Standard Model calculation is in general not shared by these models. Updated lower limits on the mass of the charged Higgs boson in Two Higgs Doublet Models of Type II are presented.
