Advertising primarily affects the demand curve. It does not directly impact the supply curve. However, a successful advertising campaign can lead to a shift in the demand curve.

Impact on Demand Curve: Effective advertising increases consumer awareness, creates a desire for the product, and can alter consumer preferences. This leads to an increase in the demand for the product. The demand curve shifts to the right.

Impact on Equilibrium Price and Quantity: A rightward shift in the demand curve results in a higher equilibrium price and a higher equilibrium quantity. Sellers, seeing increased demand, are incentivized to produce more. This increased production, combined with the higher price, leads to a greater quantity being traded in the market.

Potential for Supply Response: If the advertising campaign is very successful and sustained, it might also encourage new firms to enter the market, shifting the supply curve to the right in the long run. This would further lower the equilibrium price and increase the equilibrium quantity.
