HBO announced on Monday that due to popular demand, they’ll begin selling bottles of Tru Blood, the titular beverage from their hit show “True Blood” starting September. It’s really just blood orange soda bottled to look like the “synthetic blood from Japan” that is imbibed by the peace-loving vamps on the show as an alternative to going for the jugular. They’re available for pre-order here, but at $4 a bottle, you have to be a serious sucker to sign up. That said, I can pretty much guarantee it will be as ubiquitous at Halloween parties this year as the Thriller dance. I remember when HBO first began marketing the series premier on billboards made to look like ads for synthetic blood, I was confused about whether or not it was an actual beverage brand and had to Google it–which we all know is tantamount to a marketing bull’s eye. I guess things have come full circle now!
