It is estimated that 1.1 billion people have Internet access world-wide. That still leaves out a large number of potential Internet users, or potential costumers, depending on how one looks at it. That's probably why some entrepreneurs have been tackling the issue of how to close this divide.
One interesting approach was taken by Meraki, a Silicon Valley technology company. It developed cheap and simple network devices that allow ordinary Internet users to set up networks and share costs so that more people can connect. The company, which was named a "Technology Pioneer" at the recent World Economic Forum, has helped extending wireless Internet in about 70 countries.
