The given chart shows the total time spent by UK citizens on telephone calls, expressed in three categories, during 8 years from 1995-2002.
Looking over this chart we can mention that mobile calls are the least favourite option for UK people. But we can still see a slow growth of time spent on them during 6 years, from less than 10 billion minutes in 1995 to 20 in 2000, but after that, there was a dramatic rise to almost 50 billion minutes just in 2 years.
National and international fixed line calls were smoothly growing, without any shock events, from about 40 billion to 60 billion for past 8 eight years.
Local fixed line calls can official be called the riders of this top, overcoming other 3 types of calling. From 1995 to 1999 were rising significantly, startting at 70 billion and ending at 90 billion. But after a shocking growth there was a dificult time for them, falling down during 3 years from 90 billion to nearly 70 billion calls.
To summarize, with no doubt local fixed line calls were still the most popular option in 2002, the difference in numbers between the three categories had become not that big.
