True Blood Ad To Air During Vampire Diaries TONIGHT

Heads up, Truebies! HBO will air a 30 second ad for True Blood season 3 during tonight’s season finale of The Vampire Diaries on the CW (airs at 8/7c). We watch the show – it’s our not-so-secret guilty pleasure – so would be tuning in anyway. Still, we can’t help but chuckle that people might tune in for the first time, just to watch an ad for another show. It’s kind of awesome.
