Fascinating new blog find (via Christy) – the Extratextuals, a group blog defined as the following:

This is a blog about the media. However, with other blogs on television, film, and the media in general, we wanted to carve out a specific niche. So our blog will focus primarily on the extratextuals that surround the media. By this, we mean everything but the show itself: previews, merchandising, industry buzz, branding, interviews, posters, spatial context, temporal context, related websites, ARGs, spinoffs, spoilers, schedules, bonus materials, transmedia extras, games, YouTube clips, etc. But we’re interested in these things not to be arcane or eccentric; rather, we believe that the extratextuals often make the show what it is. Hence this blog is about the mediation of media.

In hunting for the term extratextual I also came across a wonderful study by Marianne Cantwell, all about fan knowledge and participation in the extratextual.
