1962–1975

Symbol and corporate mark as seen on most Mazda cars from the Mazda R360 until 1975.
1975–1991

Between 1975 and 1991, Mazda did not have an official symbol, only a stylized version of their name; the previous blue "m" symbol was still used in some dealerships up until the 1980s, but later on a plain blue square next to the Mazda name was often used on dealer signs and documentation.
1991-1992

In 1991, Mazda adopted a corporate symbol which was to represent a sun and a flame standing for heartfelt passion.
1992-1997

Shortly after the release of the new symbol, the design was smoothed out to reduce its similarity to Renault's. Somewhat unkindly, this badge is known as the "toilet seat" by some Miata owners, although it is more often called "Eternal Flame".
June 1997–present

A redesigned symbol was introduced in June 1997; it is a stylized "M" meant to show Mazda stretching its wings for the future. Sometimes called the "owl" badge.
