Information Warfare: The Cell Phone Revolution

As of 2017 two-thirds of the world population is using cell phones. That’s five billion people with cell phones and many of them with more than one. The gr0wth in cell phone use has been phenomenal. There were one billion users in 2003, two billion in in 2007, three billion by 2010 and four billion by 2013.

The rapid spread of cell phones had the most impact in poor countries with few phones of any kind and little or no Internet use. The cell phone became simultaneously the first phone and personal computer most people got their hands on because by 2008 most cell phones were both. In the poorest countriesmany people used texting (it's cheaper) most of the time but their cell phones give them an unprecedented ability to send, and receive information, to or from anywhere in the world. This has brought on many changes.
