Should childrenís TV programmes be taken off air?

1. Nearly every household in Britain has the familiar television set. Almost every boy and girl has watched a programme specially designed for children. However, the question of whether childrenís TV programmes are beneficial is open to debate. In this essay, the educational, social and economic factors relating to childrenís TV programmes are considered.

2. First, television has been an endless source of education for both young and old. Sesame Street, which is for younger children, has helped many of them to acquire general knowledge skills such as using the alphabet and solving basic maths problems. It has also increased the variety of vocabulary that they use.

3. From a social perspective, however, childrenís TV can be seen as exerting a negative influence. The programme, Grange Hill, for example, features swearing and stealing and the violent scenes it depicts could make children think it is necessary and normal to fight. Fighting could lead to accidents.

4. In addition, children can become addicted to television causing them to lead an unhealthy lifestyle in which they develop a lazy attitude to life. It can also be argued that an excess of TV viewing blocks childrenís imagination.

5. On the other hand, shared viewing of television programmes can generate conversation among those who have watched the same programmes. Strong opinions and stimulating discussion may result.

6. An important economic factor that needs to be considered when assessing the benefits of childrenís TV is the fact that it is a source of employment. It provides work for adults and children alike. In addition children can improve their acting skills by featuring on programmes.

7. Finally, another strong argument in favour of childrenís TV programmes is that their absence could lead to children watching unsuitable adult TV which may show considerable swearing and violence.

In conclusion, it is clear that although there are several social resons for assessing childrenís TV as having a negative influence, there are many more educational and economic arguments for why childrenís TV should be maintained.
