The United States government has started a website to help children think critically about the advertising
that is aimed at them. The new site is called Admongo. It claims to provide visitors with an "aducation"
through games and other entertainment.
A cartoon man dressed in old time pilot clothing greets visitors to Admongo. "Call me Haiz" he says upon
arrival in a rocket ship that opens up with a crazy world inside it. Dabce plays in the background as Haiz tells
visitors that they need to learn about advertising.
The Admongo website is aimed at children eight to twelve years old. Its inventors say that is the age kids
develop their critical thinking abilities. Kids that age are also a big market for advertisers.
The idea behind Admongo is to teach children three things: to identify the advertiser, to know what the
advertiser is really saying, and to know what the advertisement is trying to get the child to do.
Children learn these things through a video game. They create their own game character. They can choose
different skin colors, hairstyles, eye and mouth shapes. Then they begin a trip through ad- land. They take a
walk through the neighborhood. They seek out the advertising and capture treasures. There are ads on buses
and billboards. The players have to find all the marketing in the neighborhood before they can move on to the
next level.
The Admongo game takes players inside a home, to the advertising studio and everywhere else ads can be
found. It is a complete exploration of the world of marketing.
One such area is food marketing. The Federal Trade Commission says it is an especially big business. The
F. T. C. estimates that food, drink and fast-food restaurants spent more that one and a half billion dollars on
advertising to young people in 2009.
The F. T. C. says children are important for three reasons. They buy products. They influence parents and
caregivers to buy. And they are the future adult buyers of the products.
A recent study says most advertising aimed at children is for foods of the lowest nutritional value. First
Lady Michelle Obama has said she would like to see advertisers marketing healthy foods for children.
