Blockbuster will shutter another 300 of its stores, or 35 percnt, as parent Dish Network seeks ways to breathe new life into the video rental chain, Variety and the Denver Post report. Englewood, Colo.-based Dish purchased Blockbuster in 2011 for $320 million and continues to stand behind the brand, which it sees as an opportunity to grow its video-on-demand business among its satellite TV subscribers.
