However, the negative effect on child should not be neglected: ① A lot of unhealthy contents block children's healthy development. ②Watching TV for hours wastes a lot of valuable time that can be used for other important things like reading. This time-killing habit may harm children's profound thoughts and thinking ability.CONCLUSION: We should present new philosophy on children's TV programs producing. The producer should know well about children's needs and respect their requirements, including all kinds of rights and ideas, linking the entertainment function of these programs more closely with their education function and taking advantage of successful business models oversea, and inspiring organizations to produce more suitable programs.
