A month after Zuckerberg launched Facebook in February 2004, i2hub, another campus-only service, created by Wayne Chang, was launched. i2hub focused on peer-to-peer file sharing. At the time, both i2hub and Facebook were gaining the attention of the press and growing rapidly in users and publicity. In August 2004, Zuckerberg, Andrew McCollum, Adam D'Angelo, and Sean Parker launched a competing peer-to-peer file sharing service called Wirehog, a precursor to Facebook Platform applications.
Platform, Beacon, and Connect

On May 24, 2007, Zuckerberg announced Facebook Platform, a development platform for programmers to create social applications within Facebook. Within weeks, many applications had been built and some already had millions of users. It grew to more than 800,000 developers around the world building applications for Facebook Platform.
On November 6, 2007, Zuckerberg announced Beacon, a social advertising system that enabled people to share information with their Facebook friends based on their browsing activities on other sites. For example, eBay sellers could let friends know automatically what they have for sale via the Facebook news feed as they listed items for sale. The program came under scrutiny because of privacy concerns from groups and individual users. Zuckerberg and Facebook failed to respond to the concerns quickly, and on December 5, 2007, Zuckerberg wrote a blog post on Facebook, taking responsibility for the concerns about Beacon and offering an easier way for users to opt out of the service.
In 2007, Zuckerberg was added to MIT Technology Review's TR35 list as one of the top 35 innovators in the world under the age of 35. On July 23, 2008, Zuckerberg announced Facebook Connect, a version of Facebook Platform for users.
In a public Facebook post, Zuckerberg launched the Internet.org project in late August 2013. He explained that the primary aim of the initiative is to provide Internet access to the five billion people who are not connected as of the launch date. According to Zuckerberg, Internet.org would also create new jobs and open up new markets using a three-tier strategy. He stated in his post:
The world economy is going through a massive transition right now. The knowledge economy is the future. By bringing everyone online, we'll not only improve billions of lives, but we'll also improve our own as we benefit from the ideas and productivity they contribute to the world. Giving everyone the opportunity to connect is the foundation for enabling the knowledge economy. It is not the only thing we need to do, but it's a fundamental and necessary step.
Internet.org faced significant opposition in India, where activists said its limited internet ran counter to the idea of net neutrality; Zuckerberg said that a limited internet was better than no internet. Internet.org was shut down in India in February 2016. Zuckerberg later met with Narendra Modi, Satya Nadella and Sundar Pichai in the San Francisco Bay Area to discuss how to effectively establish affordable internet access in less developed countries. He also changed his Facebook profile picture to extend his support to Digital India to help rural communities stay connected to the internet.
