The bar chart illustrates the total number of minutes spent on three categories of telephone calls in the UK—local-fixed line, national and international-fixed line, and mobile calls—between 1995 and 2002.
Overall, local fixed-line calls were the most widely used type throughout the period, although they experienced a decline after peaking in 1999. In contrast, both national and international fixed-line calls, as well as mobile calls, showed a consistent upward trend.
In detail, the total number of minutes for local fixed-line calls increased steadily from just over 70 billion in 1995 to a peak of around 90 billion in 1999. However, this figure declined gradually to about 72 billion by the end of the period.
The number of minutes for national and international fixed-line calls also rose steadily, starting at around 38 billion in 1995 and reaching approximately 61 billion in 2002. Meanwhile, mobile calls experienced the most dramatic growth, climbing from roughly 3 billion minutes in 1995 to nearly 45 billion minutes by 2002. Notably, mobile usage in 2002 was almost threefold higher than in 1999.
