After ten years of development, China's DVD player market has entered a mature period. The sales volume of China's DVD player market maintained growth during 2003 and 2006, but the growth rate has slowed down. The sales volume of China's DVD players had its first drop in 2007, and the market in 2008 continued this trend. In 2008, affected by RMB appreciation, financial crisis, intellectual property fees and patent fees, China's DVD product export experienced unprecedented tests: high labor and expensive raw material costs, the price of DVD players were challenged again, and climate and natural disasters restricted DVD players' transportation and sales.
