4.2 billion people are still offline

For majority of the world, "Googling" and "Facebooking" are not second nature. There are currently 4.2 billion people -- 57 percent of the world -- who are still offline on a regular basis, according to the United Nations Broadband Commission. Overall growth in Internet access is expected to slump down from 8.6 percent in 2014 to 8.1 percent in 2015. Around 70 percent of mobile and fixed subscriptions are concentrated in these two regions: Asia-Pacific and the Americas.

Even though the report estimates that 60 percent of the world population should be online by 2021, the gap between the richer and poorer nations will most likely remain wide unless policy efforts are made to bridge that gap. Less developed countries have not adopted the internet with the same enthusiasm. Growing audiences in linguistically diverse areas, such as Africa, India and Southeast Asia, still proves to be a challenge. Most of the world's languages are not not represented online.
