The bar chart illustrates the amount of time spent on local fixed lines, national or international lines and mobiles calls in the United Kingdom between 1995 and 2002. Units are measured in billions of minutes.
Overall, it can be seen that the highest number of phone calls were local, while mobiles consistenly remained the lowest throughout the period. Furthermore, national/international fixed line and mobiles experienced significant growth.
In 1995, local fixed-lines started at just over 70 billion minutes. It experienced a gradual climb and reached a peak of almost 90 billion minutes in 1999. However, the figure fell steadily across three years period, returning to its initial number of roughly 72 billion minutes by 2002.
In contrast, the other two categories showed minimal fluctuations. National and international fixed-lines began at slightly below 38 billion minutes, which then climbed incrementally to finish the period at around 74 billion minutes. In the first year, calls made via mobiles were approximately 3 billion minutes. This sector saw an exponential rise, particularly after 1999, eventually peaking at about 45 million minutes in 2002 which is nearly fifteenfold increase from the start of the period.
