Dear friend, in this statement the sounds of media effect on our life does not any sense at all.
Nowadays, technology has switched our life in many aspects like popular goods exhibition by terrestrial media.
don't use to advertisement and those effect/results.
You can use switch when some thing similarity can use instead of ones. for example a worker can switch instead on one who can work like him.
Terrestrial media!! where you see this term? we have terrestrial plant/animal.
In this statement:
Advertising is a very convenient way for both customers and producers because it deals a way of purchasing and selling between them.
You have to explain why this kind of trading is convenient? you have more repetition without complete reasons and supports.
Also, your ideas are an awkward one. please at the first time wrote your purpose as a kind of map mind. so distinguished and classifying them as blueprint/main ideas like ielts Cambridge reading. Then write your support.
I mean when you write such a writing in your real exam you may take only 5 or perhaps 5.5 even when you use this kind of words that those are unusual for your essay. you have to use the correct collocation of each words that you use it.
with this subject please write another one, so I revise it again.
