The MasterCard brand was launched as Master Charge, a sub-brand of the Interbank Card Association, in June 1969, and its now-iconic red and orange circle logo was introduced for the first time.
In December 1979, Master Charge was renamed as MasterCard, retaining the circle design from the previous logo but with a new wordmark added.
In April 1990, the 1979 logo was redone, with the wordmark changed and italicized and the intersecting circles design changed to show horizontal stripes instead of a darker shade of red.
In September 1997, a drop shadow was added to the wordmark, and the number of intersecting lines between the circles were reduced. Although a new corporate logo was introduced in 2006, this logo remains in use on the cards themselves. This is still used as a secondary logo.
On July 14, 2016, the company, with its name now spelled Mastercard (with a lowercase "c"), changed its logo for the first time in 20 years. The text was moved off of the circles, and the circles were changed back to the original interlocking design, while using the same colors as the 1990 and 1997 logos. This change makes it look slightly similar to the original 1979 logo design, albeit with a darker shade of orange in the center instead of a darker shade of red. It was later universally adopted by all of Mastercard's sub-brands in October 2016.
