Question ?

Have you ever wondered why mostly foreigners are regularly feautured in Indian Ads/Indian websites ? If you go to a mall you will see mostly foreign models advertising the various products. And also if you visit any website of an Indian Company you will see a team of foreigners discussing about something. Won't it make more sense for an Indian customer to identify the product with Indian models in it ? Or is it the web designers don't get enough pictures of an Indian team ?
