Media archaeology or media archeology is a field that attempts to understand new and emerging media through close examination of the past, and especially through critical scrutiny of dominant progressivist narratives of popular commercial media such as film and television. Media archaeologists often evince strong interest in so-called dead media, noting that new media often revive and recirculate material and techniques of communication that had been lost, neglected, or obscured. Some media archaeologists are also concerned with the relationship between media fantasies and technological development, especially the ways in which ideas about imaginary or speculative media affect the media that actually emerge.
