'Sesame Street' has been called 'the longest street in the world.' That is because the television program can be seen in so many parts of the world. That program became one of America's exports soon after it was shown in New York in 1969. In the United States more than six million children watch the program regularly. Although some people do not agree to some parts of the program, parents praise it highly. Tests h ave shown that children have learned much from watching 'Sesame Street'. The children who watch it five times a week learn more than those who watch it less. In the United States the program is shown at dif ferent hours during the week in order to increase the number of children who can watch it regularly. The programs use songs, stories, jokes and pictures to give children a basic understanding of numbers, letters and human relationships. Why has 'Sesame Street' been so much more successful than other children's shows? Many reasons have been suggested, such as the educational theories of its producers, the support from both the government and businessmen, and the full use of various kinds of television skills. Perhaps another important reason is that mothers watch 'Sesame Street' together with their children. This is partly because famous film stars often appear on 'Sesame Street'. But the best reason for the success of the program may be that it makes every child watching it feel able to learn. The child finds himself learning, and he wants to l earn more. 1.
