Great NY Times history lesson of how NYC became a tech town post financial crisis with some great stories on Tim Armstrong, Mike Bloomberg and Kevin Ryan.
In the late summer of 2000, Timothy Armstrong, at 29, qualified as an internet veteran. Mr. Armstrong helped create or became a senior manager at a string of ventures, and had a solid track record in internet sales and marketing when he met with Omid Kordestani, head of sales at Google. The company was looking to expand, and Mr. Kordestani arranged a meeting between Mr. Armstrong and its founders, Larry Page and Sergey Brin, in Silicon Valley.
