The line graph illustrates how many individuals used five distinctive communication services worldwide in a decade between 1998 and 2008.
Overall, there was an increase in the number of users of all five communication services examined, with cellular phone service witnessing the most substantial growth to become by far the most common from 2002 onwards.
The number of subscribers to landline service started at 15 million, after which it experienced a gradual rise to exactly 20 million in 2006, before ending the period at roughly 19 million. Similarly, not until the year 2002 did people start using fixed broadband and mobile broadband, and the figures for these two services increased slightly, reaching approximately 4 million in the final year.
5 million people subscribed to cellular phone service in the beginning of the period, followed by a gradual rise to about 18 million four years later, and a final substantial growth to just over 65 million in 2008. The figure for internet service can be seen in the similar pattern, but to a lesser extent, which increased from just under 5 million in 1998 to 20 million eight years later, followed by a final levelling off towards the end of the period.
