Abstract :
The achievements of the three main e+e- Factories have been impressive. The KEK B-Factory has achieved a peak luminosity of 1.7x1034 cm-2 sec-1 and the PEP-II B- Factory has reached 1.2x1034 cm-2 sec-1 while the DAFNE Phi-Factory has obtained 1.5x1032 cm-2 sec-1. Early in the B-Factory running, CP violation in the B meson system was found to be consistent with the prediction of the Standard Model. Now all three factories are integrating as much luminosity as they can in order to look for rare decay channels that may have a rate that differs from the value predicted by the Standard Model and therefore hint at New Physics. There are two newer factories that have started or are about to start. The Tau-charm factory at CESR has been delivering luminosity to the CLEO detector and BEPCII, the newest Tau-charm e+e- factory located at IHEP in Beijing, has just started commissioning. I will give a status report on the recent accomplishments of all five factories and will show what these facilities have for plans to further improve performance.
