Reader Jonathan Hendry wrote in with some interesting backstory related to my post about Apple, Inc. becoming a defense contractor:

Actually, [Steve] Jobs isn't a stranger to selling to the Pentagon. While his products are thought of as consumer electronics, there was a time when his best customers were in very serious industries like defense and high finance (UBS, Swissbank, Merrill Lynch, First Chicago, Soros, etc).

Jobs' company NeXT Computer (which Apple bought in 1997, bringing him back into the fold) sold quite a few machines to the spooks in the early 90s. The spy agencies liked how quickly software could be developed on the NeXT operating system. I personally interviewed for a defense-oriented NeXT programming job with, I think, Lockheed-Martin back in 1994, my senior year of college. (I don't recall what the system was, but I know I would have needed a security clearance - they gave me the forms to fill out. I wound up taking a job in Chicago that put me on a contract at Swissbank.)

Around 1993, NeXT stopped making computers, changing to an OS-only strategy. Supposedly they had to run the assembly line for a little while longer, in order to fulfill the spare-parts stock requirements of their defense contracts.

I expect Mr. Jobs is feeling a little deja vu right now.

Jonathan's email reminded me that the Pentagon has recently begun integrating Apple computers to bolster its network security. So, high-profile defense contracts are nothing new to the most powerful man in business.
