Poltergeist HDTV Sale Ad?

The remake of Poltergeist is coming out soon, so why aren’t we seeing Poltergeist-themed ads for selling new TV sets? They could simply show some family shopping at some big box retailer (like Best Buy) when their little girl walks up to a big TV set, and a ghost pops out of it telling them what great deals they can get on new HD TVs. Then the announcer says: “Great deals on all the best new HD TVs,” and the little girl says: “They’re here!”
