Three Snapshots in the History of Asymmetric B-Factories

I will present three snapshots in time in the development and use of asymmetric B-factories. The first snapshot, in the late eighties, will describe the origin of the idea and the early debates on its feasibility. Next we will jump to today and briefly review the results and the underlying physics picture that has emerged from the work at the two asymmetric B-factories, PEPII and KEKB. Finally, we will jump ten years into the future and speculate on what the evolution of B-factories may bring, with two orders of magnitude more data and consequently much higher precision measurements.
