The consumers spent less than $\$10$ billion on DVDs in the years 2000 and 2002.

The graph shows the amount spent on the y-axis and the year on the x-axis. Note that there are two points whose y-values are less than 10 billion dollars. These are the first two points from the left, which represent the years 2000 and 2002. Thus, consumers spent less than $\$10$ billion on DVDs in the years 2000 and 2002.
