No one can avoid being influenced by advertisements. Much as we may pride ourselves on our good

taste, we are no longer free to choose the things we wants, for advertising exerts a subtle influence on

us. In their efforts to persuade us to buy this or that product, advertisers have made a close study of

human nature and have classified all our little weaknesses.

Advertisers discovered years ago that all of us love to get something for nothing. An advertisement

which begins with the magic word free can rarely go wrong. These days, advertisers not only offer free

samples, but free cars, free houses, and free trips round the world as well. They devise hundreds of

competitions which will enable us to win huge sums of money. Radio and television have made it possible

for advertisers to capture the attention of millions of people in this way.
