Advertising is be good and bad thing. The good part about it is it increases(dramatically) your sales. The bad thing about it is there is too much junk food that appeals to children.
Advertising is a good thing to both the consumer and the manufacturer because the consumer gets to know the product and the manufacturer gains if it sells through advertising.
Having Ads is the best way to go. It becomes bad if in a certain amount of time you do not make more money in the business as you had to put out for the AD.
This is like asking if information retention is better or information circulation. How would it sound to give birth without letting anyone know what has one given birth to. A product needs marketing and advertising is the means to do that or else.....
Advertising has good points in keeping us in the know of things, when new products or improved products, etc are marketed.
The bad point of advertising is the extremes some advertisers go to and the repetitiveness. Some ads/commercials beat all around the bush before they get to the point.
