The power of advertising over kids
Advertising has an influence on everyone in one
way or another, but it especially has had an
influence on children.
Advertising influences children's choice of toys.
If a television commercial displays children
laughing and playing children think it must be a
great toy, regardless of the type. For example,
my three old desperately wants a skateboard
for Christmas. Every time he sees a skateboard
commercial, he gets excited. He believes that if
he had a skateboard, he would instantly have
the same fun and skill as the boys on television
Another influence advertising has had is on the
clothes children want to wear. Clothes from
Wal-Mart and K-Mart are no longer satisfactory
Brand names such as GAP. Tommy Hilfiger.
American Eagle are much more appealing to
them. My teenage daughter is constantly
looking through catalogs and magazines,
examining each outfit down to the last detail.
She continuously wants to change her
wardrobe to keep up with the latest fashion
trends and most popular brand names.
