This article uses a historical perspective to describe the development of the profession of technical communication through three ages: Brass, Beige, and Glass. I compare this development to the growth of the academic discipline and both to the explosion of noninstitutional technical communication--the growing body of tactical technical communication that happens outside of organizations and institutions. This leads me to describe today as the Golden Age of technical communication. I conclude that we should broaden the scope of technical communication and spread it as a set of skills valuable for everyone to learn.
