Positive and negative effects for audience ;
It has been argued that , now a days TV is very important in our life so it is considered as a useful resource and TV is part of technology that cause to increases information about their surrounding world ,they can choose the best way , but this question is propounded is TV a useful for children ?
As far as , I know TV has few benefits for children .
there are some good educational programs but these days some children
do not use properly of TV for instance they just use TV useless programs so for these children is not useful.
I’m convinced that TV has a positive influence on learning by that I mean TV leads to abetter grasp of the subject but I agree that many children at the present time spend too much their time with TV even in their leisure time so it isn’t good because children should use other facilities expect TV they must use another things for example newspaper ,internet , and library .
also a lot of advertising is targeted at children and this makes TV viewing very unattractive .
to sum up , TV for learning new things seems to be dependent on how use people ,however many of discussion about TV‘s influence on society has been negative because it reduces social activities .

TV now a days ;

who do you believe only to wish you could be with such a people for life?
from my point of view The "television" that pick to stay with for life. I think the "the television" not so much the people do to big age difference.
The technology of television has changed in most of the countries since its early days that mechanical system invented in 1884.
AT the present time most of countries are using digital TV but in some counties are using analog TV like in my country .

Analog television, like all other motion picture systems, and it is used for motion pictures to create a smooth moving image.
digital television Sound and pictures are converted into a digital format and compressed,
in 2008-2012 television services in the UK will be completely digital
In most cases digital TV can improve the quality of TV pictures and sound.
