Firstly, the producers can introduce their new products to consumers throuth ads. I hear that the ad produces a good image of a product, and that leads to consumer brand loyalty. It means consumers are loyal to a certain product and keep buying it. Also, they are willing to pay more. Secondly, by this way, the producers can increase sales and enlarge the market what they did have. In other words, more sales mean lower production costs but more advertising means higher costs to the consumer. In the end the winner is of course the producers.

 On the other hand, with the development of the ads, there are many ads what is not ture in modern society. The consumers get in trouble with trusting it. But it just a small bad part of the ads after all.

 Above all, a good ad can bring much profit to producers. I think ads are more good than bad.
