Coca-Cola was originally invented by John S. Pemberton in 1886.
In 1887, the now-familiar Spencerian script was first used within the logo. Compared to today's version, the script varied depending on its application, and the word "Trademark" also commonly appeared at the bottom of the wordmark's first letter "C".
A new logo was released for Coca-Cola in 1890, which featured more swirls. The logo deemed unpopular and they quickly changed back in 1891.
By 1891, the script began to be standardised.
Since 1941, the word "Trademark" was removed from the logo, and the wordmark itself evolved into what would become the company's longest-used design to date.
In 1987, Coca-Cola began using a slightly straightened-up bolder version of the script. This was used until a revamp in 2003.
