The Vampire Diaries uses HTC and other android phones in every episode for the past 5 seasons; integrating the devices into the show's entire structure instead of a single episode. The phones have become a "life source" for all the characters who use the phones in order to get them out of dilemmas in every episode. They even talk to the villains on their cell phones. That must have been an awkward conversation... "Hey, I know we hate each other but we don't have to be old fashion. Can I have yo number?"
