Since the times of its appearance television has played a very important role in people’s lives. It’s considered to be one of the most powerful media sources. The first sketches of moving objects in electronic devices were made in 1878, later in the 20-s and 30-s of the XX century the first real television appeared. Television has consequently become a cheap form of entertainment for people worldwide. The first TVs were white and black, and only in 1967 the citizens of our country saw colour television. Nowadays television has progressed and changed a lot for the better. Nearly every family has one or two TVs in their homes, and these TVs differ a lot from the past ones. Contemporary TV sets offer digital television (DTV), high-definition television (HDTV) and other new technologies. There are also hundreds of thematic channels instead of two and three, which were back in the 60-s. Television has lots of advantages, for example, keeps us informed, entertained and in some cases even educated. It can also get the family together in the evenings. However, there are also some disadvantages. It cuts people from the real world. Some people get addicted to it and can’t stop watching. Another disadvantage is the content sometimes shown. First of all, there is so much advertising, that it occupies the majority of television time. Secondly, there is lots of violence and cruelty on TV nowadays. It gets difficult to find something neutral to watch. Nevertheless, television has obviously changed the society, and it’s probably used more than any other type of mass media.
