Abstract: Particle physics has made remarkable advances when stored, cooled beams of antiprotons became available. Soon after, scientists called for polarized antiprotons in order to explore the spin degrees of freedom in antiproton-induced reactions. In the past 20 years, many clever ideas on how to satisfy this request have been produced, however, only recently has there been experimental activity in this field. I will review some of the history, what is going on at present, and where this might possibly lead.
