The line graph portrays the total amount of time sped on the telephone calls of three types in the UK over a seven-year period from 1995 to 2002. Overall, by having more meticulous review it is evident that the minutes spent on the national and international calls along with mobile calls have rose substantively whereas the time spend on the local calls fluctuated before coming to the total at the first year of the period.
At first glance, it is obvious that the minutes spent on the national and the international calls had a continuous gradual increase staring at 37 billion in 1995 and eventually surpassing 60 billion. Analogously the total amount of time used for mobile calls also had a upwards trends beginning approximately at 3 billion mark and roughly reaching 10 billion in 1998 which was followed by a more rapid gain until exceeding 45 billion in 2002.
In the other hand, local fixed calls at first had a steady rise by being roughly at 90 billion in the year 1998 which was followed by a negligible gain in 1999. Onwards from 1999, however, the time used for local calls had a steady decline by coming doe to the same amount in 1995 by being slightly above 70 billion in 2002.
