Advertising is definitely an art as it uses the components of ethos, pathos and logos to persuade the customers. I agree to the statement given by William Bernbach. It is real step by step techniques which is used by companies to persuade the customers to like their product and then buy it. The ad agencies and people who work create an advertisement are artists with immense knack for creativity and originality. Every great ad is a masterpiece and a work of art. That is the reason we remember famous ads even after decades.
