Advertisements Going South?

Quite a lot of recent advertisements have been based around a South Indian character.
I feel more and more South Indian characters started featuring in North Indian films and advertisements after that phase in Indian cinema that saw Quick Gun Murugan, and to a smaller extent, Om Shanti Om.

Here are a few advertisements, South(Indian)ernized:-

1. The good ol' Center Fresh Ad

2. Voltas AC

3. Mahindra Duro DZ




4. Ebay




Is this a trend?

Also, people get very disappointed when I don't talk in a South Indian accent while talking in English or Hindi. I've at times had people requesting me to talk with a South Indian accent.
