The chart illustrates data about the number of minutes of local, mobiles, and national calls in Australia between 2001 and 2008.
Overall, it is easy to mention that local calls dominated over other categories throughout the period. Despite the fact that the number of mobiles witnessed a significant surge by the end of the period covered, it remained the least popular.
In the year 2001, the quantity of local calls were 72 billions, sharply surging during next four years. The year 2005 marked a turning point, reaching a peak with the number of 90 billions. Notwithstanding the fact that by the year 2008 indicators declined to only 72, it gained the lead. Mobiles were not common at all in the year 2001, having only 2 billions. During the next seven years the number experienced a significant increase, reaching 46 billions in 2008. However, this category was of the bottom priority for all years.
National and international calls were rather stabilized from 2001 to 2008. In the year 2001, this category had 38 billions, taking the second place between others. For the next several years indicators rose steadily. By the end of the period there were 61 billions, remaining the same position as at the beginning.
