Making an advertisement for television often costs more than a move．For example, a two-hour movie costs $ 6 million to make．A TV commercial can cost more than $ 6 000 a second．And that does not include cost of paying for air time(电视节目开始的时间)．Which is more valuable, the program or the ad? In terms of money--and making money is what television is all about the commercial is by far the more important．
Research, market testing, talent, time and money--all come together to make us want to buy a product．No matter how bad we think a commercial is, it works．The sales of Charm went up once the ads began．TV commercials actually buy their way into our head．We, in turn, buy the product．
And the ads work because so much time an attention are given them．Here are some rules of commercial ad making．If you want to get the low middle-class buyer, make sure the announcer has a tough, manly voice．Put some people in the ad who work with their hands．If you want to sell to upper-class audience, make sure that the house, the furniture, and the hair style are the types that the group identifies (识别) with．If you want the buyer feel superior to the character selling the product, then make that person so stupid or silly that everyone will feel great about himself or herself
We laugh at commercials．We don't think we pay that much attention them．But evidence shows we are kidding ourselves．The making of a commercial that costs so much money is not kid stuff．It's big, big business．And it's telling us what to think, what we need, and what to buy．To put simply, the TV commercial is a form of brainwashing．
