Facebook on Thursday unveiled an app to allow people around the world with mobile phones but no Internet access to access online services for health, education and basic communications. The Internet.org app is being released first in Zambia, and is to be rolled out in other countries where Internet access is lacking or unaffordable, Facebook said. Over 85 percent of the worlds population lives in areas with existing cellular coverage, yet only about 30 percent of the total population accesses the Internet, Facebooks Guy Rosen said in a blog post. Affordability and awareness are significant barriers to Internet adoption for many and today we are introducing the Internet.org app to make the Internet accessible to more people by providing a set of free basic services.
