Dynamical breaking of supersymmetry was long thought to be an exceptional phenomenon, but recent developments have altered this view. A question of great interest in the current framework is the value of the underlying scale of supersymmetry breaking. The ``little hierarchy'' problem suggests that supersymmetry should be broken at low energies. Within one class of models, low energy breaking can be achieved as a consequence of symmetries, without requiring odd coincidences. The low energy theories are distinguished by the presence or absence of R symmetries; in either case, and especially the latter, one often finds modifications of the minimal gauge-mediated spectrum which can further ameliorate problems of fine-tuning. Various natural mechanisms exist to solve the \ensuremathμ problem in this framework.
