Why 4.4 Billion People Still Don't Have Internet Access

The question now is: How will the next billion people get online? What technologies are needed to make that happen?
The report said cost, digital literacy and infrastructure are some of the barriers that keep people offline. But there's also a lack of incentive, meaning some people don't use the Internet, even though they could, because they don't see any point. In the United States, a Pew study found that a majority of offline Americans think the Internet isn't relevant to them or too difficult to use. Only 7 percent are off the grid and unable to physically access the Internet.
Facebook has tried to address the incentive issue by making a text version of its website called "Facebook Zero." It has proved very popular in Africa, where it can be accessed free on a non-smartphone.
