Television and radio.
Television and radio are very much alike. They have similar technological base and are based on transmission of the radio signal.
The first to appear was the radio and it was rather spread. In the 20th century almost every average family had the radio.
It plays the same functions as television and television developed from it. These functions are: informative, educative, cultural, social and the function to entertain. But nowadays all its functions have become less important and now it is turned on to listen to music or some radio broadcast. So entertaining has become the leading function.
It is very convenient to spread information to masses because it is used all over the world and it can be found almost everywhere. With the development of technology it has become more important. Besides it can be used not only to entertain and to get information but also to communicate with each other because it is the easiest way to transmit the signal. Television and radio are very much interconnected and not only by their technological base but also by the broadcast they have. Radio has the same effect on people as television because is considered to give the true information too and make people believe they are the participants of the actions that they hear.
The same problem that has every kind of mass media is advertisement. Sponsors, slogans and opinions of costumers appear on the radio every day and just bother listeners. Television is even worse, because on television you can not only hear it but also see it. It interrupts the film or the TV show. But in spite of everything, this advertisement is necessary for press, television, radio, because it is the only way to get profit.
Like television radio has developed its own genres. Nowadays the quiz programmes and panel games as well as live-broadcast shows are one of the most popular. They are rather educative and entertaining and you can get real pleasure from playing the quiz and even get some prizes. From this point of view radio is more convenient than television, because you don't need to go to the TV studio and play the quiz, the only thing you need is to dial a number of the radio studio and enjoy yourself. Of course there are several TV quizzes that don't demand the presence of the player and you can participate in it using the telephone too. But such programmes as a rule are not very popular and don't have a large audience. To the contrary the TV quizzes with the presence of the player are one of the most popular and frequently watched.
