We know little about the propaganda early homo-sapiens used to promote technology except that they visually idealized the subject of their pursuit. They painted on walls images of animals they hunted. More recently, examples of propaganda in support of technology can be found in public health campaigns, commercial advertisements, academic policies, popular entertainment, political speeches and in military propaganda.
In popular discourse, debate often coalesces around pro- and anti-technology ideals. Some hold that a strict analysis reveals the term "technology" to veil a euphemism in colloquial arguments that appeal to belief and emotion. Analysis of pro-technology propaganda includes both a general review of how propaganda supports the spread of various technologies, investigation of how the term "technology" is popularly used euphemistically for a group of technologies, and how that implicit group of technologies is promoted.
Belief in or skepticism of "technology" offers themes for popular literature, art, opinion and political platforms. Popular debate about "technology" often revolves around the reliability of a belief in the likelihood of beneficial discovery and invention. The debate at other times hinges on whether a particular group of technological endeavors are worthwhile.
Corporations and industrial associations promote the spread of what they and some of their critics call "technology" through scholarships, grants, press releases, conferences and other informational techniques that some consider to be tools for propaganda. Through the 20th century, whatever technology was the latest topic of interest in the news tended to fuel art, fiction and popular non-fiction literature. Companies, and governments often managed perceptions of their technological decisions by influencing how the public saw those technologies.
