Internet.org programme focuses on connecting unreachable parts of the world.
The revelation came during a Q&A session on Facebook, where Zuckerberg answered questions from his 32 million fans including Sir Richard Branson.
However, Zuckerberg also said that for now, the Internet.org programme is focusing upon the countries with the most unconnected people, which hints that it could take some time for free internet to hit Europe.
The Telegraph cited Sir Richard’s question as asking : "I share your view that it is crucial to connect the two thirds of the world that don’t currently have access to the internet. What do you think will be the biggest benefits of this?"
To which Zuckerberg replied saying: "When we talk about connecting the world, most people talk about the clear benefits to all the people who will get internet access and don’t have it today."
"Those benefits are many: access to education, health information, jobs and so on. Many people estimate that for every 1bn people we connect, we’ll raise more than 100m out of poverty.
During the one-hour session Zuckerberg also answered questions regarding Oculus, saying that he sees the headset serving the same purpose as his social media platforms, which is to connect people from different locations through a medium, and is also likely to allow users to create 3D films and sharing them with friends.
