I usually listen to the radio in the mornings when I go to the work. I like the news and to know what is happening in the world. However I think that people listening to the radio less than before because of new technology. Now you can listen whatever you prefer for 24 hours a day and to choose between several/many channels, surfing the internet ....There are many options to watch or to listen at any given moment that you want it. Before there were few channels and people had to conformed with what was scheduled on that day on television or radio.
Today the programs are have difficulty keeping the attention of the audience, especially the current affairs programmes and the news (with its 24 hour news cycle). In my opinion the television doesn´t offer the necessary quality. Personally, I don´t like reality shows, soap operas, or talents contests...There are some good programmes and hit series but not many.
On the other hand, I think that people are constantly exposed bad news, which can have harmful effects on them. Researchers have demostrated that people can feel sadly and depressed when they are exposed long time to negative news for a long time. That´s why people tend to focus on their personal problems so frequently.
Mass media should think about how they broadcast the news and the effects that it has on people. However, the emotionals stories increase the audience because people tend to empathize and unfortunately the audience is more and more important for mainstream media and for it to survive in this world.

Nice work! I like the new choices and options but I also like the singing contests...

I didn't read over the other corrections. I thought I'd just start fresh and give it a whirl for you. 

Practising writing Practicing (how we spell it here in the USA) is if you are saying, "here I am at this moment practicing my writing" but if you want to label your essay as "A" practice "IN" writing, as a noun, then it would be "Practice Writing" as a title or even better "My Practice Writing" or "A Practice in Writing"  or "My Writing Practice" or "An Essay for Writing Practice" (which I like best). Having a title staring with two "ing" words somehow just isn't really "right" even though your English is fine. This is some serious fine-tuning, but I think you might enjoy a native not just saying what's grammatically correct, but what "sounds" better. 

I usually listen to the radio in the mornings when I go to the work. You know, this is pretty good English, but it's not what I think you really wanted to say! My guess is that what you really wanted to say was that you usually listen to the radio in the morning as you are going to work. The way you said it it could be interpreted as you listen to music when you arrive at work. To make this the most clear, that you are actually listening to the radio as you are on your way to work you would say I usually listen to the radion in the morning as I go to work or on my way to work. What I would probably say is: I listen to the radio on my way to work in the morning in the car or as I'm driving to work. I like the news and to know what happen in the world. I'm pretty sure that what happen doesn't exist in English. I like the news and to know what's happening in the world. However There's usually a comma after however when you use it as the first word in a sentence. I think that people are listening to the radio less than before because of new technology. Now you can listen to what you prefer for 24 hours and to Do you understand why I crossed that out? It's because choose relates back to now you can. Now you can listen and choose. choose between several channels, surfing the internet .... If this is for a test please, please, please take out those dreaded dots! :D One period will suffice. This is choppy, stoccato English remember? ha ha ha. There are many posibilities to watch or to listen at moment what you want it. There's got to be a better way to say that because it's not quite right. I would say You can watch or listen to whatever you want, whenever you want to. Before there was were a few channels and so people had to conformed with (conform to) You need to choose what tense you want and stick to it! People had to conform to or people comformed to - never had to conformed - YIKES. :) what was scheduled that day on television or radio.
Today the programs are many difficulties to keep attention to the audience, I'm not exactly sure what you meant there, but I think it might be: Today programs have a tough time keeping the attention of their audiences, especially the 24 hour direct news and current affairs programs especially the current affairs programmes and news 24 hours in direct. In my opinion the television doesn´t offer necessary quality. I think this would sound more "native": In my opinion television doesn't offer the necessary quality any more. If you want to get really fancy and impress your teacher you could write: doesn't offer the requisite quality any more. Personally, I don´t like reality shows, soop operas, Oops - that's probably a typo but a soop or soup opera is when the actors are singing and drinking soup at the same time ha ha ha but what you see on TV are soap operas because most of the time they should have their mouths washed out with soap! That was a joke. Could you understand it? talents contest...There are those Spanish keep the sentence going at any cost dots! PERIOD. Personally, I don't like reality shows, soap operas or talent contests. PERIOD, done, finished, entire sentence and there's a capital coming for the next sentence to start a whole new sentence nice and fresh. There are some good programmes Is that a British spelling or something? In America it's programs. and hit series but not many.
On the other hand, I think that people are constantly exposed to bad news and it can have harmful effects in on them. Researchers have demostrated that people can feel sadly and depresed depressed when they are exposed a long time to negative news. That´s why I think you mean to say that people who watch a lot of news tend to focus on their personal problems more. "That's why" would be saying that people focus on their problems as a direct result of the news - as a very direct result. Even better might be to say that there is a correlation between people that watch the news and increased levels of focussing on personal problems and depression.  people tend to focus on their personal problems frequently.
Mass media should thinks how they broadcast news and the effects that cause in people. To think is kind of a human trait that Mass media wouldn't do. What you might say is that Mass media should evaluate or moderate how they broadcast news taking into account the effects that it can cause in people.  However, the emotionals emotional is an adjective so there are no emotionals in English. It's always just emotional stories increase the audience because people tend to empathize and unfortunately the audience is more and more important for mainstream media and for to survive in this world Ok, this is the end of your excellent essay so let's finish it in a way that seems more like a native would say it. I'll just give it a try:

In the end it's the emotional stories that will increase audience numbers because people tend to empathize with the people in the stories and in order for mainstream media to survive in this competetive new world they must focus on what their audiences want rather than what would make their audiences happier. 

There you go my friend. Sorry for all the red writing. I just wanted to explain every little suggestion fully and give you lots of ideas. I agree with you 100% on what you wrote in your essay and I think it's a terrific essay! Great job.

Pretty sophisticated writing there, all makes sense just a few grammatical errors :) I couldn't agree more with your views about television, I also think people do listen to the radio but not the informative or educational channels. Recently we had this program on UK television where you watch other people watch tv, I think it's crazy but it seems to get an audience.
