There are a number of theories attempting to address technology, which tend to be associated with the disciplines of science and technology studies (STS) and communication studies. Most generally, the theories attempt to address the relationship between technology and society and prompt questions about agency, determinism/autonomy, and teleonomy.
If forced, one might categorize them into social and group theories. Additionally, one might distinguish between descriptive and critical theories. Descriptive theories attempt to address the definition and substance of technology, the ways it has emerged, changed and its relation to the human/social sphere. More substantively it addresses the extent of which technology is autonomous and how much force it has in determining human practice or social structure. Critical theories of technology often take a descriptive theory as their basis and articulate concerns, examining what way the relationship can be changed. The authors mentioned in this article are those that have some concern with technology or media, though they often borrow from one another and of course build upon seminal theorists that preceded them.
Critical theory goes beyond a descriptive account of how things are, to examine why they have come to be that way, and how they might otherwise be. Critical theory asks whose interests are being served by the status quo and assesses the potential of future alternatives to better serve social justice. According to Geuss's definition, "a critical theory, then, is a reflective theory which gives agents a kind of knowledge inherently productive of enlightenment and emancipation' (1964). Marcuse argued that whilst matters of technology design are often presented as neutral technical choices in fact they manifest political or moral values. Critical theory is a form of archaeology that attempt to get beneath common-sense understandings in order to reveal the power relationships and interests determining particular technological configuration and use.
Perhaps the most developed contemporary critical theory of technology is contained in the works of Andrew Feenberg including 'Transforming Technology' (2002).
