The line graph illustrates the average cost that American customers spent on mobile and landline phone services annually over a 10-year period.
Overall, spending on residential phone services dramatically declined, while popularity of mobile services increased sharply throughout a decade. Also, both of services met at the same record in 2006.
In 2001, spending on mobile phone services began by merely $200, while the amount of annual expenditure on the residential phone services was around $700. Over the following five years, expenditure on landline phone services gradually dropped below $600, whereas expenditure on cell phone services rose to just over $500.
In 2006 cell phones overtook landline phones, and the services became equal in popularity with customers' annual expenditure of about $550. Then, cell phone expenses rose to approximately $750 in 2010, making nearly a fourfold jump relatively to its initial figure in 2001. Meanwhile, spending on residential phone services experienced a steep fall in 2007 and went on to steadily decrease for the rest of the period.
