The provided line graph represents money earnings from sold cinema tickets and DVD sales in the USA and abroad during the period from 2001 to 2010. It illustrates the gradual proportional rise in all kinds of sales for that period of time except DVD sales in the USA which had a tendency to downfall slightly when it came to the end of the decade.
The graph shows that international cinema sales and international DVD sales both went up steadily with the simultaneous peak at 2004, and the latter was almost twice as low as first. Contrary to international sales, DVDs and cinema tickets sales in the USA went in different directions as cinema sales kept rising slowly during the time when DVDs sales went steadily down after the peak in 2004.
The supplied data shows that US and international markets of DVDs sales had a difference of income around 10 billions back in 2001, where the last one had a lower amount of income. But in the year of 2009 they became even with the number of 20 billion and after that international DVD sales grew up when the US DVDs sales steadily went down. As the US cinema tickets sales were almost stable at the point of 10 billion with slight rise, the international sales increased from 20 billion in 2001 to 32 billion in 2010.
As we can see from this line graph, the USA market of cinema tickets sales and DVD sales stayed stable or went down during the mentioned period of time while same international markets both moved upwards.
