A glimpse at the provided chart discloses the interesting differences among a diversity of types of UK telephone calls. While the total number of minutes of local fixed line dwindled after a gradual rise in earlier years, the usage of not only mobile but also national and international fixed line saw their optimistic and steady rises.
The total local fixed line call duration reached the peak of more than 90 billion minutes in 1999 from about 72 billion in 1995. After that, the trend reversed and the number was gradually declined to nearly 70 in 2002.
However, long distance fixed line calls seems to be still demanded by the market with a steady growth in the total number of minutes from about 37 billion in 1995 to almost 60 billion in 2002.
Mobiles seems to be another emerging type of call with the total minutes mildly risen from no more than 3 billion in 1995, to approx. 10 billion in 1998. This is followed by an exponential climbing to about 45 billion in 2002 of the new century.
Although local fixed line calls still dominated the overall telephone calls as of the total minutes in 2002, it is evident that the mobile calls was going to win the highland within years.
