No, I do not believe that advertisements should be banned. Just as television shows and movies have the right to profit, so does advertisers. Granted sometimes the advertisement themselves and the content have no meaning to the viewer, some may gain information from the advertisement. I am sure that at some point an ad has been useful to everyone.
Banning advertisement is not only harmful to companies it can also be quite harmful to the citizens that the advertisements are meant for. Banning advertisements would diminish rights including free speech and others, it would also limit the amount of money that a company can make. With no advertisements consumers would not get notified on the different products that could be useful to them. You see as the consumers buy things they need the companies take that info and create ads that give us options of different products we may want or need. In wanting money companies create products that we want at a price that we can afford if they don't do that they will not be making very much money. Companies that trick people may make quite a bit of money but people will catch on and those companies will not be making money for long.
