As one would expect, confusion is bound to arise especially when one happens to be in the same industry. Incidentally, both the Karan's are Punjabi and are originally from Delhi. What's even more interesting is that their fathers were college mates and seem to know each other.
Apparently both the Karan's have now swapped their roles, which is creating a lot of bewilderment in the commercials and TV area. Earlier on one of the Karan's was focusing on commercials and the other Karan was primarily focusing on TV. So, it was easy then given that one was known as a TV guy and the other as an Ad guy.
Well now that they have crossed each other's path, it's only going to add to the confusion.
We suggest you add another K, Karan?
