It has been 25 years since the inauguration of the "detector" collaboration for PEP-II during the Nov 30 - Dec 4, 1993 collaboration meeting number 1. The BaBar christening came later, we needed to establish the Collaboration Council for that.
Now, 25 years later, PEP-II and the BaBar detector were actually built(!). We published 576 papers (and counting) on CP violation and many other things in what can only be described as a hugely successful collaboration. A good time to reminisce, contemplate what we have learned, and celebrate!
