Correct me if I’m wrong but I dont remember big companies coming to SD en mass at any point in time. To my knowledge, SD has been an incubator of start-up companies and has never been home to lots of corporate giants. The successful ones grew big enough to be acquired by an industry giant and typically get consolidated into the parents ops somewhere else. Its been that way as long as I can remember things (i.e. back to the mid-80’s). SD has always attracted entrepreneurs, creative minds and researchers that are drawn to exericising their passion in our beautiful climate/envirnoment.
The big companies that are hear typically have had relatively small satelitte ops here. Outside of Qualcomm, what major employers, I’m talking 5 to 10K employees, have been headquartered in SD in the last 20 years outside of the 2 big defense contractors that disappeared in the early 90’s?
