How would successful advertising campaign affect the elasticity of demand for that advertised product?

A successful advertising campaign can decrease the price elasticity of demand for the advertised product, making it more inelastic. By increasing brand awareness, creating perceived value, and fostering customer loyalty, consumers may become less sensitive to price changes. This means that even if the price increases, the quantity demanded may not decline as significantly, leading to higher revenue for the company. Additionally, effective advertising can differentiate the product from competitors, further solidifying its inelastic demand.
