Short answers, pulled from the story.
PopMatters was founded by Sarah Zupko and launched in late 1999. Zupko had previously established PopCultures, a cultural studies academic resource site, before creating PopMatters as a sister site focused on original essays and cultural criticism.
PopMatters publishes reviews, interviews, and essays covering music, television, films, books, video games, comics, sports, theater, visual arts, travel, and the internet. It describes itself as an international online magazine of cultural criticism.
By the fall of 2005, PopMatters exceeded one million readers per month. The site had grown from a weekly publication to a five-days-a-week magazine format by that point.
Yes. From 2006 onward, PopMatters produced syndicated columns for McClatchy-Tribune News Service. By 2009 there were four different pop culture columns running each week through that arrangement.
The PopMatters Book Imprint published four books in a series with Counterpoint/Soft Skull in 2008-2009, including China Underground by Zachary Mexico and Apocalypse Jukebox by Edward Whitelock and David Janssen. In May 2012 it also published Joss Whedon: The Complete Companion, edited by Mary Money, with Titan Books.
Notable PopMatters contributors include David Weigel, political reporter for Slate; Steven Hyden, staff writer for Grantland; J.C. Maçek III, writer and film producer; documentarian Rodger Jacobs; and Rob Horning, executive editor of The New Inquiry. Karen Zarker serves as managing editor.
