If products are sold on the basis of quality, then why companies pay crores of rupees to cricketers?

Answer 1

I am also really in loss to understand the logic of advertisement through cricketers and film stars for any product spending crores of rupees, as according to me people will not buy a product just because these people have advertised the same if the product is not good. If the product is good even without advertisement people will buy the same.
May be because Companies can deduct the advertisement expenses in order to reduce the tax payable.

Answer 2

It is called advertising. They need to get their name out where people see it.
