As if that other vampire-riffic phenomenon couldn't get any bigger, we were peeping the Terapeak Hot DVDs section this morning and noticed a TV series atop the list... For those keeping score, your crazy-colored vampire eyes don't deceive you: that's HBO's True Blood laying a whuppin' on the former undead champs. But unlike Twilight, which has more than its share of detractors, we've heard almost exclusively good things about the HBO series. Now in its second season, the show stars Oscar-winning actress Anna Paquin as Sookie Stackhouse, a telepathic waitress, and chronicles the mystifying events of a small town in Louisiana. Below is a 90-day total sales trend for "True Blood," produced by Terapeak's All Sites package: We're not actually sure what's produced such a spike -- the DVDs were released several months ago, and the show's second season only just began -- but then we also haven't had a chance to really bite into the television series... (hah!) Maybe if there weren't so many freakin' Twilight books to finish?
