A review will be given of the current status of the muon magnetic moment, both theory and experiment. It is argued that the value of the muon anomaly is sensitive to physics beyond the standard model, for example supersymmetry. We will describe the experiment and the recently published result from our 2000 data set. We will also discuss briefly the uncertainies in the hadronic cotribution to the theoretical number. The resulting theory uncertainty considerably degrades the comparison between theory and experiment, and we discuss the prospects for improvements in the future.
