# SAGE milestone text -- 1 Nov 2011

### From GHN

My understanding is that SAGE was intended for continental air defense. Note that it is the Canadian SAGE installation from North Bay, Ontario that is currently held by the Boston Computer Museum.

Original Citation:

In 1951 the Massachusetts Institute of Technology undertook the development of *an air defense system for the United States*. The centerpiece of this defense system was a large digital computer originally developed at MIT. The MIT Lincoln Laboratory was formed to carry out the initial development of this system and the first of some 23 SAGE control centers was completed in 1958. SAGE was the forerunner of today’s digital computer networks.
