Recently discovered new mechanisms for primordial black hole (PBH) formation make them a plausible candidate for dark matter in a broad range of models. For example, PBHs appear to be a generic dark matter candidate in supersymmetric models. Another example: fermions provided with Yukawa interactions can form PBH during the radiation dominated era or matter dominated era. I will review the new formation scenarios for PBH, as well as the astrophysical consequences and the ongoing search for PBH dark matter.
