We present a class of AdS4 vacua of type IIB string theory for which the lowest-lying graviton is allowed to obtain a small mass, motivated by the holographic duality between these solutions and a certain class of 3d N=4 superconformal field theories. We derive a universal formula for the mass of the graviton, comment on its qualitative attributes and extend our discussion to closely-related bimetric models.
