Name that company

I trace my roots back to 1904, when a son of Italian immigrants founded the Bank of Italy in San Francisco, which morphed over time to become the world’s largest commercial bank by the 1930s. I’ve gobbled up lots of companies, including credit card giant MBNA, U.S. Trust, FleetBoston Financial (which traced its roots to 1784) and even Merrill Lynch. Today, based in Charlotte, N.C., I sport a market value recently near $262 billion. I serve about 66 million customers via roughly 4,300 retail financial centers, and about 31 million customers bank with me using mobile devices. Who am I?
