Dish Network Corp. acquired Blockbuster Inc. in a bankruptcy auction for about $320 million, a move that could see the second-largest U.S. satellite TV provider tapping the movie rental chain’s online content to strengthen its offerings, Reuters reported. Dish, led by satellite billionaire Charlie Ergen, trumped at least three other bidders, including activist investor Carl Icahn, for the one-time leader in video rentals. The deal marks the second purchase of a bankrupt company by Dish. Last month, Dish got a nod from a bankruptcy court to buy hybrid satellite and land-based communications company DBSD North America for about $1.4 billion.
