Coke is evidently not the only company using sexual innuendo.
Pepsi, Mcdonald, Burger King
Many advertisement use sexual innuendos to attract consumers to their products. The idea of sex prompts us into a very suggestible state of mind which means that if we were told to consume a product in that state of mind, we were more likely to subconsciously want to consume that product. The more exposure we have to that advertisement, the more we are susceptible to it.
If sex sells, it is no wonder that these are major brands in the market if these subliminal messages are purposely intended to induce us to be more suggestible to these brands.
