      The US government has started a website, Admongo, to help children think critically about

the advertising aimed at them. It claims to provide visitors with an "education" 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. Spacey dance

music plays in the background as Haiz tells visitors that  they need to learn  about advertising.

      Its inventors say eight to twelve  years old is the age kids d evelop 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, hair styles, eye and mouth shapes. Then they begin a trip through

ad-land, where 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 (FTC) says it is a big business.

The FTC estimates that food, drink and fast-food restaurants spent more than one and a half billion

dollars on advertising to young people in 2009.

     The FTC 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.
