Band 6+: 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 amount of money spent on cell phone, domestic and global fixed-line services in America over the course of 9 years, starting from 2001.

Overall, it is clear that in this 9-year period, there was a similar trend in all statics, with the exception of domestic fixed-line services. Additionally, mobile phone services registered dramatic increases and had the highest rates throughout the period.

In 2001, the yearly expenditure on cell phone services stood at about $200 (the lowest figure that year). Between 2001 and 2006, the average figure amount spent on mobile phone rose to around $500. Over the next four years, it witnessed a sharply increase of nearly $800, becoming the top position among three types of services surveyed.

Also in the first year, the amount of money spent on national and international fixed-line services were higher at around $250 and $700, respectively. However, these two types of services witnessed inverse trend, with the former decreasing to $500 and the latter increasing to $300 in 2006. Over the course of 4 years, while national fixed-line services continued to decrease to only $400, global fixed-line services remained unchanged.
