Why Focus on Fizzies

I find it a little irritating that most of the focus and discussion revolves around coke the fizzy drink when the beverage although what the company was built around is not the only thing this outfit derives its income from.Instead of boring the crapp out of us all by trying to decide if you like coke pepsi or any other of the horrible brews can anybody tell me exactly what proportion coke is of Ccl,s business.
