This will be effective among college students. This advertising stunt for Mars aims to make the target audience to experience the brand in a new way. Well, its interactive kind of advertising. The campaign- 'Messages from Mars' - provides consumers with a set of stickers featuring the complete alphabet in Mars typography, including punctuation marks. Thus the bar actually became a platform for communication where people can create their own messages and can give it to friends. Good one for lovers. Others won't waste much time over it, I think.
