If you were the game master, what challenge would you like to throw to Ranbir?
Well,any game or a challenge is designed keeping in mind certains conditions :
the game master;
the product(Pepsi); and
a three tier link between the above three which makes a perfect formula for success
grasps the audience attention
relates well with the product / theme
stronger brand recall
People love dolphin's . They are simply cute. So is Ranbir.
The color of water and the entire theme matches with Pepsi's base color - Blue.
Blue also symbolizes: youth, spirituality, truth and peace. All these , which the generations of today "youngistaan" looks up to.
Presenting such a challenge is something which all can watch and the "word-of-mouth" in such things is great for a higher brand recall.
