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 the popularity of mobile services increased sharply throughout the decade. Additionally, both services met at the same record in 2006.

In 2001, spending on mobile phone services began at 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 equally popular with customers’ annual expenditure of about $550. Then, cell phone expenses rose to approximately $750 in 2010, making nearly a fourfold jump relative to their initial figure in 2001. Meanwhile, spending on residential phone services experienced a steep fall in 2007 and continued to steadily decrease for the rest of the period.
