Many people believe that watching television has resulted in lower reading standards in schools. However, the link between television and printed books is not as simple as that. In many cases, television actually encourages people to read; for example, when a book is turned into a TV series, its sales often go up. One study of this link examined six-year-old children who were viewing a special series of 15-minute programs at school. The series was designed to encourage love of books, as well as to develop the basic mechanical skills of reading. Each program is an animated film of a children's book. The story is read aloud and certain key phrases from the book appear on the screen, beneath the picture. Whenever a word is read, it is also highlighted on the TV screen. One finding was that watching these programs was very important to the children. If anything prevented them from seeing a program, they were very disappointed. What's more, they wanted to read the books which the different parts of the series were based on. The programs also gave the children more confidence when looking at these books. As a result of their familiarity with the stories, they would sit in pairs and read the stories aloud to each other. On each occasion, the children showed great sympathy when discussing a character in a book because they themselves had been moved when watching the character on television.
