Coca-Cola Zero or Coke Zero is a product of the Coca-Cola Company. It is a low-calorie (0.75 calories per liter) variation of Coca-Cola specifically marketed to males, who were shown to associate ‘diet’ drinks with women.
The Coca-Cola Zero logo has generally featured the script Coca-Cola logo in red with white trim on a black background, with the word “zero” underneath in lower case in the geometric typeface Avenir (or a customised version of it). Some details have varied from country to country. The British logo, for example, originally had the “o” taking a spiral form. In the U.S., the letters decline in weight over the course of the word.
