不同意就好了
I don't think the statement is correct.
理由1.Everything has a reason why it apears.Ads are business activity for one company.It can help the company become known
2.Ads is to show their products and can change the consumers' ideas about what they need and want.
3.without ads,we could not know what a new product can help with.
4.the profits from its effect is much higher than the cost a company spend on the ads
