"The Po-Mo Page: Postmodern, Postmodernism, Postmodernity" provides a concise yet substantive introduction to postmodernity, differentiating between the historical condition and the intentional movement in arts, culture, philosophy and politics. Quoting some major theorists (e.g., Lyotard, Jameson, Benjamin), the author illustrates how the term "postmodern" has been used in various fields (history, economics, politics, art) with particular attention to uses made by Frederic Jameson. Most helpful is the table of "contrasting tendencies" which, while admittedly a very modernist approach, identifies two dozen ways in which postmodernity seems to have features that oppose or contradict tendencies that have been recognized as hallmarks of modernity. Created by Martin Irvine, the Founding Director and Associate Professor of the Communication, Culture, and Technology at Georgetown University, the visually appealing webpage has no links to other sources, but is one link among several grouped on his faculty webpage under the heading of Media Theory.
