Mass Media plays a very important role in modern society. The most important means of media include radio, television, newspapers, magazines, and Internet. These sources inform, educate and somehow entertain us. My favourite media resource is Internet. It represents all sources in one. If I want to read the daily news, I go online. If I want to read magazines about things that interest me, I address Internet. When I want to listen to the radio or to watch a new film, again I turn on my computer. Basically, Internet is the media resource which has successfully displaced all other means from use. If I had no Internet at all, I would choose television. This is another media resource which I find engaging and useful. Radio is another media source I like. I listen to music almost all day long. Speaking about printed press, I should say that my parents are subscribed to a local newspaper. They also buy some magazines from time to time. My mum likes reading “Elle” and “Cosmopolitan” magazines and my dad usually buys magazines about motor and racing cars.
