There is clear evidence that TV advertising influences what children buy.
It is clear from numerous studies that TV advertising influences what children buy.
Recent research demonstrates that TV advertising influences children's spending habits.
Many parents think that TV advertising influences their children. This view is supported by the findings of a recent study, which show a clear link between television advertisements and children's spending habits.
The findings also reveal that most children are unaware of the persuasive purpose of advertising.
There is little evidence that children understand the persuasive intent of advertising.
The results contradict claims that advertising is unrelated to children's spending habits.
Manufacturers argue that it is difficult to prove that advertising alone influences what children buy.

confident • completely sure that sth will happen in the way that you want or expect: I'm quite confident that you'll get the job. The team feels confident of winning.
