Year Company Founded: 1893

Logo Designer: Gould & Associates (1967), Landor Associates (1996), Arnell (2008)

Company Founder: Caleb Bradham

Caleb Bradham, the founder of the company, scribbled a design which would become the logo for the company. The design was changed only slightly until 1962 when the word "cola" was dropped, and it just became Pepsi. The logo was a bolded "Pepsi" with a red, white, and blue bottle cap in the background. The logo was modernized 5 times from 1971 to 2005, each time becoming more sleek and defined.
