International Telephone Call Minutes (Nikisha Tan-Mishra, Group 3) (^o^)


This graph shows the total number of minutes used in international telephone calls from 2005 to 2012, with the numbers on the y-axis being in millions. 

As you can see, there has been a gradual increase every year, other than 2011, with a drastic increase between 2009 and 2010. This means that more people make international calls over the years, probably due to our improvement in technology.
