If the particle carrier of the gravitational force had a mass, gravity could behave differently as GR on cosmological scales thereby potentially tackling the dark energy and cosmological constant problems. I will review the cosmological behavior of this model as well as some of its extensions. In particular I will present some exact FLRW solutions in generalized massive gravity where the mass parameters are naturally promoted to Lorentz-invariant functions of the Stuckelberg fields. The existence of stable self-accelerating solutions will be discussed as well as some relevant phenomenology.
