Band 9: The graph below shows consumers’ average annual expenditure on cell phone, national and international fixed-line and services in America between 2001 and 2010.

The line graph illustrates the average yearly spending by consumers in America on three types of telephone services: cell phone services, national fixed-line services, and international fixed-line services between 2001 and 2010.

Overall, expenditure on cell phone services increased significantly over the period, while spending on national fixed-line services declined steadily. In contrast, expenditure on international fixed-line services remained relatively stable with only a slight increase.

In 2001, Americans spent approximately $200 per year on cell phone services. This figure rose gradually to around $450 in 2005 and then increased sharply, reaching about $750 by 2010. The most noticeable growth occurred after 2006, when spending on mobile phones overtook that on national fixed-line services.

On the other hand, expenditure on national fixed-line services started at about $700 in 2001, making it the highest among the three categories. However, it decreased continuously throughout the decade, falling to roughly $400 by 2010.

Regarding international fixed-line services, spending was around $250 in 2001. It increased to approximately $300 in 2002 and then remained almost unchanged for the rest of the period, ending slightly above $300 in 2010.
