The bar chart depicts the overall figure for minutes of three different types of telephones, namely local, national and international and mobiles over a period of seven years, from 1995 to 2002, measured in billions.
Overall, it is evident that there was an upward trend in two out of three categories in the period shown. Additionally, it is also visible that the local- fixed line was attributed for by far the most dominant category among all.
Looking at the information in more detail, in 1995, there were over 70 billion minutes of local calls, which was nearly double that of national and international telephones, with approximately 38 billion minutes of calls. The total minutes of calls of mobiles in the same year was the least favored in the UK with merely around 3 million minutes. In the following four years, the calling minutes of local telephones had risen significantly and reached 90 billion minutes in 1999. The figures for national and international and mobiles telephones witnessed a similarly increasing trend, which were at 50 and about 24 billions of calls respectively.
In the following three years, while local telephones went down dramatically by about 17 billion in terms of calling minutes, by contrast, figures for that of mobile phones rose strikingly and reached around 46 billion minutes of calls in 2002. In addition, there was a slight increase by over 10 minutes of call in the same period.
