So if there wasn’t enough troubling news in the world, now comes word that Transformers has sold 8.3 million DVDs in North America alone since its debut on October 16, with 4.5 million of those coming in a single day. After pulling in over $315 million domestically at the box office ($700 million-plus worldwide), the movie has already become the top-selling October DVD release of all time, as well as the best-selling HD-DVD ever, with 190,000 copies of the latter now sitting on coffee tables next to recently popped copies of Halo 3 and Maxim Magazine.
