Bank of America and Transamerica were separated, with the latter company continuing in the insurance sector. However, federal banking regulators prohibited Bank of America's interstate banking activity, and Bank of America's domestic banks outside California were forced into a separate company that eventually became First Interstate Bancorp, later acquired by Wells Fargo and Company in 1996. Only in the 1980s, with a change in federal banking legislation and regulation, could Bank of America again expand its domestic consumer banking activity outside California.
