Based on a rich holographic framework correlating a family of three-dimensional SCFTs and IIB supergravity solutions on AdS4xM6, we present a top-down string theory embedding of massive AdS gravity. We describe the mechanism under which the initially massless AdS_4 graviton acquires a mass and present the relevant mass formula. Consequently, we discuss the corresponding biometric gravity embedding as well as the breakdown of the effective theory under the scope of the AdS distance conjecture, while finally, we make reference to certain interesting, relevant recent developments.
