The line graph compares average yearly spending by Americans on mobile andlandline phone services from 2001 to 2010.It is clear that spending on landline phones fell steadily over the 10-year period,while mobile phone expenditure rose quickly. The year 2006 marks the point atwhich expenditure on mobile services overtook that for residential phone services.In 2001, US consumers spent an average of nearly $700 on residential phone services,compared to only around $200 on cell phone services. Over the following five years,average yearly spending on landlines dropped by nearly $200. By contrast,expenditure on mobiles rose by approximately $300.
