Beginning to tell you about my favourite newspaper, firstly I would like to stress that the mass media and especially press play very important role in our lives.Needless to say that the mass media have done and continue doing much to excite and to maintain our interest in every aspect of the life in Russia. But I want to draw your attention to the work of press and its role in the life of society.The press is one of those few means of getting information, which exists in almost all parts of the world. Reading different newspapers and magazines, we learn about recent political, economical and cultural events in Russia and abroad, about international relations and progressive views, about ordinary and extraordinary things and cases. That is why I think it necessary that people should read newspapers and magazines.As for me, my favourite newspaper is “Moskovskiy Komsomolets” (“MK”, in brief). I am sure you have heard about this newspaper and have had a chance to read it. I suppose, it gives us a great amount of information and quickly and vividly reflects current and important events on its pages.The principal vital and actual problems are always discussed by the reporters of “Moskovskiy Komsomolets” and this feature attracts me much. On the pages of “MK” we also can find broad daylights of the political life of the country – this is another good tradition and positive particularity which is liked by its readers.For all items and saturation coverage of occasions this newspaper offers a lot of columns and headings with brief and interesting headlines.It goes without saying that the most exciting reports and latest news are always published on the first page of “MK” so that the readers could familiarize with them at once. To my mind, it’s very convenient!Recently a great amount of advertisements have appeared on the news pages and on the pages of “MK” too. I consider this is wrong: advertisements occupy the space which could be used for news or reviews and must be published only as special separate periodicals. They reduce the quality of the newspaper as a source of information and affect its prestige, and this point should be taken into account.On the whole my favourite newspaper meets my requirements and I hope that it will be printed in future.
