This is a video of Coke Zero new advertisement.
Coke as a carbonated soft drink is always under attack of reducing the health of the people drinking it. Sales of its soft drink are reaching a stagnant stage. Therefore it seems that right now coke is trying to go into Coke Zero which will attract more people with its zero sugar content.
This advertisement induce consumer to believing Coke Zero being a wonderful invention comparable to a time machine whereby it is actually just changing sugar to artificial sweetener. Coke has always placed a huge emphasis on marketing due to the fact that what they are selling really is just soft drink and it has many substitutes to it like coffee or milk. What marketing help Coke achieve is that brand loyalty and making Coca-Cola more than just a soft drink. Maybe a way of life, or things you must enjoy in life.
There is a reason why Coke has so much capital to spend for its advertisements and why they are spending so much on it. It means marketing works.
