Answer:
Quality advertisement sells product even before the buyer set up for a transaction. Companies spend huge amount in making sure a catchy advert is presented to the mass population which are the targeted audience.
No matter how much is spent in making this advertisement available, it is surely believed that the company covers their expenses as they add it up in the product to be sold. Using the advertisement of Airtel Network in which " Data is Life" is quoted after the advertisememt, the content of this advert shows the abundance of food stuff in a woman's kitchen making her to feel free without managing or lacking, in the other hand another woman is shown in her own kitchen lacking all that is supposed to be available in the kitchen and she don't have at enough to sustain her in cooking. So the aim was that with Data life is made easier and there won't be unecesary management.
Knowing that everyone understands what it means to lack food stuff in the kitchen and in the other way round, what it means to have in abundance this advert was made simpler for everyone to understand and the idea already sold.
The smaller firm also sell their own products through smaller advertisement online, offline and by bill posting too. They make their own sales but not as large as the big companies.
