When we were kid, we use to saw cartoons either with cat, mouse or dog, nor super heroes. But now a day kids watch cartoons with many well know characters. Like Sherlock Holmes, Mr. Bin, Charlie Chaplin etc. This is really good. Because of these cartoons, kids get to know about big characters and later they may read or watch the real one.
It can also have some bad reaction. If the cartoon draw a picture which doesn't has similarities or give bad impression about that character then kids won't like them even before they get to know the real one.
