After accounting for only a small sliver of home video sales since it won the high-definition video war with HD DVD, Blu-ray Disc is finally beginning to show some real clout in the video store. Home Media magazine observes that 36 percent of total unit sales of Watchmen , which debuted at the top of the sales and rental charts last week, could be attributed to Blu-ray Disc sales. The trade publication observed that the results demonstrate that "the format is fast moving out of the early adopter phase and into the mainstream." The stop-action animated film Coraline finished in second place with 18 percent of its sales coming from Blu-ray. The 3D film is packaged with four sets of 3D glasses.
