Television is the invention of the latest decades. The fact which is undoubtedly true is that this invention has influenced the human life .We can't prove wheter it's totally good or bad because watching TV has its pros and cons as well, but let me present my point of view.
Personally I'm of the opinion that the diversity of so-called entertaining programmes comes from the laziness of people. I mean there are really more interesting and less time-consuming 'hobbies' which could broaden a mind instead of minimizing our inerests. Famous soap operas for instance.. I can't stand why people always complain about their problems and simultaneously they watch a TV show which presents some troubles of others .. I mean if I had really serious problems I wouldn't watch them at all.
In my opinion such shows only fill some empty spaces. Moreover watching television is connected with some possabilities to get sick, for instance to have some problems with eyes or a spine, or even get addicted.
Well, on the other hand, I reckon that there are some valuable channels about the environment or foreign ones which are educational let's say. But do we really need that ? That's the question. I suppose it's just another step in our 'pace-increasing' nowadays life . The desire to make 'it' faster, to get more information in less time. And I don't think that's a good perspective for the future.
To draw a conclusion, I'd say it's worth remarking that waching television is not genereally good or bed. Personally, I think there are more drawbacks, but that's only my opinion.
