As we people have characters which reflect us, so the brands have the same thing which reflect the brands as well. If we can change our clothes then the brands can do the same. If we look at the Google, we would find that in the various occasions Google modify their logo to let the people feel the taste of that occasion. So the MTV do. They even go for a project which is called MTV Hats (Header Art Treatments).
So, in Bangladesh we should do such activity to make our brands more visible and more cultural.
