Its really surprising to see such changes in the logo....
I remember Zee TV CEO telling few years back that changes in logo is inevitable in today's world. But this change is like going backwards considering logo design process.......
I read somewhere that logo was re-designed by a french design studio which are experts in all these things but it finally depends on client also.
So it seems it's like old wine in new bottle....
Fashion industry also resort to these kind of things & changes are done to perceive & distinguish the product.
