"In 2009, major banks controlled 45 percent of checking account business, according to Mike Moebs, an analyst whose firm, Moebs Services, has been gathering publicly available data on banks for 28 years. He estimates that by the middle of 2012 at the latest, the big banks' share of that market will have fallen to a third, representing a loss of millions of customers and billions of dollars."
