respectively.

However

,

rentals

experienced a downward trend, which slightly decreased in 2003 and

then

continually dropped to just under 60,000 in 2011.

Conversely

,

sales

of

DVD

in 2002 was under 50,000 but represented an upward trend until 2007, which indicated a peak of

sales

at over 210,000 and it was the highest

sales

in the graph. After that, there was a gradual decrease until 2011, accounting for around 180,000 and still the most popular among all types in 2011. We can see that VHS was the second most popular of

sales

in 2002, which comprised approximately 85,000. Interestingly, it disappeared after 2005 and was never shown again. In comparison, the number of Blu-ray

sales

just started in 2007 but it grew slowly reaching around 65,000 in the year 2011.
