We shall review simplified Z’ models as explanations for discrepancies between measurements of certain neutral current B meson decays and Standard Model predictions. We provide estimates of LHC and future collider sensitivity. Then a more complete model is introduced: The Third Family Hypercharge Model, which also explains some coarse features of the fermion mass spectrum. Finally, we chart the space of anomaly-free SM x U(1)_F gauge symmetric models, where U(1)_F can be family dependent.
