Yes, advertisement provides a boost in the purchases of the product in question. Efficient promotional and advertisement activities highlight the product and distinguish it from other products. The consumer does not have perfect information about the variety that exists in the economy; advertisement aids the consumption process for the consumer and adds to the sales of the producers of the product. In markets like oligopoly, the competition in the market is intense. Thus, the need to display the product on sale as a favourable one is more intense in such a market.

Consumers willingly or otherwise are affected due to advertisements. For example, a consumer develops trust in a product that is endorsed and advertised by celebrities, and prefers it over other products. The persuasive nature of advertisement attracts the attention of consumers instantly. The brands and labels that are preferred by people and that shape their life style are largely dependent on the influence advertisements have on their life. Advertisements have been successful in building loyal consumer bases, while making an emotional bond with the consumers. The consumers tend to blindly follow what is advertised and looks attractive to them.

Advertisement has resulted in a major change in the consumer's choice patterns. From fashion to daily need products, everything is influenced by what is seen on the television screens, and on social media due to promotions by influencers and celebrities.
