Coca Cola could be considered the earliest "energy drink" - although not marketed as such - it was one of the first carbonated drinks to contain caffeine.

The drink was first made in 1886 - where it supposedly had a very small level of cocaine in it - due to the extract of coca leaf being an ingredient. However, given that the formula has always remained secret - this may simply be an embellishment. 

The Diet Coke range actually contains about 32% more caffeine than the standard coke formula.

Coca-Cola Blak had the highest amount of caffeine of any coca-cola drink, but has since been discontinued.
