As is shown in the chart, mobile phone subscriptions grew rapidly from 2000 to 2008. We can also find out that developing countries are the driving force for such a rapid growth. According to the chart, mobile phone subscription number in developing countries increased to 8 times from around 0.5 billion to 4 billion, while subscription number only increased twice from around 0.5 billion to 1 billion in developed countries.
I think there are two main reasons for such a great contrast. First of all, developing countries have much larger population than developed countries. For example, China and India nearly have half of the total population of the world. China has the most mobile-phone users right now, which increased greatly from 2000 to 2008. It is the same in India and other developing countries.
…Secondly, developing countries have been enjoying strong economic growth in recent years. As a result, people in most developing countries are richer and richer, especially in China, so they can afford to buy such necessities, including mobile phones, as the prices continue to drop greatly in the past years.
Thus, we can conclude that as economy grows strongly in developing countries, people in these countries can afford more different products.
