The first Airways Traffic Control Center was established at Newark on
December 1, 1935. Centers at Chicago and Cleveland would soon follow.
They were initially operated by the airlines with the expectation that the
federal government would assume control of them. That occurred in July
1936. As more Centers were established in the following years more
airways became controlled.

Steven, can you recommend a good "History of the Airways" book that covers
all this kind of stuff?

I am better versed than average on the history of aviation, but I'm pretty
fuzzy on the details of ATC history.

Thanks!
