Diet Pop sales. CAP

Yesterday I was reading an article on coke sales and how they have been declining for years. This year alone sales volume went down at least 3%. What do you guys think these companies should do to increase there sales? This is a question that I think will be huge for marketing firms doing Diet Soda marketing campaigns. The problem that these companies are facing is the new ready to drink coffee, energy drinks and all the other new options consumers have in the market place that didnt exsist 5 years ago. It will be intresting to see what these compnays do in the following years.
