While Facebook and Reliance Communication are both going to derive huge benefit out of this initiative, the users also stand to benefit a lot from this.
Reliance Communication will obviously garner hordes of new subscribers with this initiative. If they offer free internet access for Facebook and few other prominent websites, people will not mind switching from their existing providers to Reliance. Internet.org is a Facebook initiative and for users accessing internet through this initiative, Facebook will become their gateway to internet. Facebook’s next growth phase is going to come from countries like India, where there are still hundreds of millions of people yet to get taste of internet. For them, through this initiative, Facebook will be the default platform they will access. Obviously the users stand to benefit because they will get Facebook access along with some prominent other websites for free.
