This old newsletter, launched in the pre-Internet area in 1976, has become one of the most respected personal finance sites in the US.
As the name implies, Bankrate provides a lot of information about US market bank fees, mortgages and credit cards, but is also a source of personal financial advice in areas such as financial planning, retirement and investments.
