According to latest research television has no positive impact on children's brain development.

A study published in German magazine for doctors, television and DVD that are designed for children do more harm than good to the development of child's brain. Babies who watch television cannot process all the changing images and sounds they see and hear, Professor Manfred Spitzer of Ulm said.

Researchers say that the most harm is seen when television learning substitutes grown-up and siblings reading. In one experiment, babies aged 9 to 12 months old were listening to grown-up reading them in Chinese, while the other group watched the same stories on television. The results showed that children who were read Chinese, could recognize Chinese sounds in two months, while those who watched television stories did not managed to learn anything.

In another research it was proven that in families where children were read to quite often, the vocabulary of a child was richer and children knew 8 percent more words than average. Otherwise, children who watched baby TV or DVD showed 20 percent lower results.
