Bloomberg writes "Northern Rock Downfall Boosts Member-Owned Building Societies", which discusses the popularity of savings accounts in the U.K.'s building societies, which are similar to credit unions. The article says, "U.K. building societies from Swindon-based Nationwide, the largest, to Century of Edinburgh, the smallest, are gaining because of depositor concerns about the security of money held at banks weakened by the global credit crisis. Owned by their customers, building societies get about 70 percent of their funds from deposits, compared with 30 percent at Northern Rock.
