You should also add more specific examples. Actually, wait, that's not exactly right. You should add specific examples, period, as you do not have any at all at the moment. You have written an entire essay on television's influence on culture without mentioning a single specific television program.
Governments usually use the media such as Tvs to generate false news to get public support.
For example? Gov't X reported Y, which we know to be false because of Z. This had a series of negative effects, A, B, C, D, etc.
Countries usually try to export their culture to other countries by producing cartoons for kids and movies for the rest of people. Sometimes these cartoons have a awful influence on kids mind because of differences between culture and lead to ruin kid's mind.
For example? Country X produces cartoon Y, which can be seen as exporting value set Z. This has ravaged culture A, by resulting in C, D, etc.
The movies have it's unconscious special effect on elder too.
And again, for example? By now you get the general idea. Go through the essay, and add specific examples throughout to prove your points, and your essay will be much stronger.
