Television now plays such … important role in so many people’s
lives that it is essential for us to try to decide whether it’s … blessing
or … curse. Obviously … television has both advantages and disadvantages.
But do … former outweigh … latter?
Television, as it is often said, keeps one informed about current
events, allows one to follow … latest developments in … science and
… politics, and offers … endless series of programmes which are both
instructive and stimulating. … most distant countries and … strangest
customs are brought right into … sitting room. It could be argued
that … radio performs this service just as well; but on … television
everything is much more living, much more real. Yet, here again there
is … danger. … television screen itself has … terrible, almost physical
fascination force. We get so used to looking at its movements, so
dependent on its flickering pictures that it begins to dominate our
lives. … friend of mine told me … other day that his television set had
broken down and that he and his family had suddenly found that they
had far more … time to do things, and that they had actually begun
to talk to each other again. It makes one think, doesn’t it?
There are many other arguments for
and against … television. … poor quality
of its programmes is often criticised.
It is undoubtedly … great comfort for
many lonely elderly people. And does
it corrupt or instruct our children? I
think we must realise that … television
in itself is neither good nor bad. It is
the uses to which it is put that determine
its value to … society.
