The bar chart, which covers an eight year period, records how long people talked for in the UK on their mobile phones or used a fixed line, whether local, national or international.
Calls made locally using a landline phone ranged between 70 billion and 90 billion minutes between 1995 and 2002 with higher usage being noted in 1998 and the following year at 90 billion minutes. National and international calls using a fixed line had a gradual increase from 35 billion minutes in 1995 to 60 billion minutes eight years later. Similarly, mobile calls went up gradually. They began at around 5 billion minutes in the first three years and by 2002 reached 45 billion minutes of talking time.
Throughout the eight year period British people used their local fixed line the most and their mobiles the least. In addition, speaking nationally and internationally via a fixed line as well as a mobile increased in popularity while using a fixed line for local calls returned back to its 1995 figure of 70 billion minutes.
