The bar chart illustrates the percentage of children watching TV daily in the period between 1998 and 2008. It is obvious that the overall trend shows a trough. As can be seen from the chart, the percentage of children watching TV was gradually decreasing before 2003, from 80% to 65%. Then they remained stable between 2003 and 2007, staying at approximately 55%. However, this number dramatically jumped to about 75% in the following year. There are many reasons contributing to the fluctuation of the bar chart. Firstly, children can use Internet instead of TV, which may have caused the percentage to decline until 2003. Secondly, the quality of TV might have improved, which kept the number of under-age viewers steady from 2003 to 2007. Digital TV launched in 2008, fascinating a large number of children to watch TV, which is why the percentage rocketed. For example, children can enjoy a fun on a programs playing cartoon all days. All in all, because of the Internet, quality improvements and digital TV launching, the whole trend of the percentage of children watching TV goes through a trough.
