Summary
In September 2006, Facebook made two changes that transformed it from a college-oriented directory into a mass-market social platform: it introduced the News Feed and it opened registration to the general public. On September 5, 2006, Facebook launched the News Feed, an automatically generated, continuously refreshing stream of updates about a user’s friends — status changes, new friendships, photos, and profile edits — displayed on the home page. Three weeks later, on September 26, 2006, the company removed its long-standing requirement that members belong to a recognized network, allowing anyone at least 13 years old with a valid email address to join.
These changes established the core mechanics — an algorithmic feed and unrestricted membership — on which Facebook’s growth to more than a billion users would later rest.
Facebook’s Growth Trajectory in 2006
From Harvard to the World
Facebook launched in February 2004 as “Thefacebook,” restricted to Harvard students with a .harvard.edu email address. Its creator, Mark Zuckerberg (born May 14, 1984), had been a sophomore at Harvard when he built the first version. The service expanded to other Ivy League universities within weeks, then to all accredited U.S. and Canadian universities by 2005. In September 2005, it extended to high schools, and in early 2006 opened to employees of corporations including Apple and Microsoft with verified work email domains.
User Numbers
Facebook’s registered user count at key 2006 milestones:
- January 2006: approximately 7 million users (all university- or corporate-network-verified)
- August 2006 (immediately before open registration): approximately 9–12 million users
- December 2006 (after open registration): approximately 12–14 million users
- August 2007 (one year after open registration): approximately 100 million users — a nearly 10× increase in 12 months
This growth curve illustrated the compressive effect of open registration: the university-gated period had taken Facebook from 0 to ~12 million users in two years; open registration added the same number in weeks and continued doubling at a pace the gated model could not have achieved.
The News Feed Launch and User Revolt
What News Feed Changed
The News Feed, developed primarily by engineer Ruchi Sanghvi and a small product team, replaced Facebook’s homepage — which had previously shown a user’s own profile summary — with an algorithmically ranked stream of friends’ recent activity. Every action a friend took on the platform — making a new friend, joining a group, changing their relationship status, uploading a photo, posting on someone’s wall — now appeared in a timestamped stream on the viewer’s home page.
The underlying information had always been technically available on each friend’s profile, but the News Feed aggregated and surfaced it automatically, removing the need to visit individual profiles. This was the crucial design shift: Facebook went from a directory (static profiles you visited) to a feed (dynamic stream that came to you).
The User Revolt
When the News Feed activated on September 5, 2006, the response was immediate and overwhelming opposition. Many users objected that the feed made previously dispersed information visible in a single broadcast format that felt invasive — broadcasting relationship changes, group memberships, and activity in a way that had previously required deliberate investigation.
A protest group titled “Students Against Facebook News Feed”, created within hours by Northwestern University student Ben Parr, grew to approximately 100,000 members within one day and peaked at 700,000+ members — then one of the fastest-growing Facebook Groups in the platform’s history. The protest generated mainstream media coverage.
Zuckerberg’s first response, a post titled “Calm down. Breathe. We hear you,” defended the feature but acknowledged the backlash. Within days Facebook added granular privacy controls allowing users to control which of their activities appeared in others’ feeds, and Zuckerberg published a more conciliatory second letter. The company did not reverse the News Feed. Within months, the feature had become so central to the user experience that its removal would have been unthinkable.
The 2006 “Feedgate” became a formative case study in product rollout dynamics: a feature that initially triggered mass objection became indispensable through habitual use and incremental privacy controls. The pattern — aggressive product change, user revolt, partial privacy accommodation, habit formation — recurred in Facebook’s history with timeline redesigns, the “like” button expansion, and the Cambridge Analytica data-sharing practices.
Open Registration
On September 26, 2006, exactly three weeks after the News Feed launch, Facebook dropped its network requirement and opened to anyone aged 13 or older with a valid email address. The expansion was accompanied by additional privacy settings acknowledging the concerns raised earlier in September. Open registration removed the structural constraint that had distinguished Facebook from rivals such as MySpace (which had no registration requirement), positioning it to compete for the general internet population.
The competitive context mattered: in August 2006, MySpace had just surpassed 100 million accounts, making it by far the dominant social network. Facebook’s 9–12 million users made it a distant second. Open registration was partly a response to that competitive pressure and partly a natural evolution of a network whose value grew with each additional user.
The Rejected Yahoo Offer
Facebook’s 2006 momentum drew acquisition interest. During 2006, Yahoo pursued Facebook in talks that reportedly reached approximately $1 billion — a negotiation that CEO Terry Semel directly participated in. Zuckerberg, then 22 years old, declined to sell after initially showing interest; accounts of the negotiation indicate he wanted $1.5 billion and that Yahoo’s board refused, ultimately offering $900 million, which Zuckerberg rejected.
Zuckerberg’s explanation for the rejection — that he wanted to build something that changed how people communicate, not sell the company — was consistent with the pattern of refusing to be distracted from product development. The decision became a frequently cited example of founder conviction: Facebook’s valuation would rise to approximately $500 million (in a Microsoft investment at that implied price) in 2007, then to $15 billion (in a second Microsoft investment) in late 2007, then to a $104 billion IPO in 2012.
The contrast with Myspace — sold to News Corp for $580 million in 2005 and subsequently mismanaged into irrelevance — illustrated the long-run advantage of founder control and mission focus over near-term exit.
Significance
Facebook’s September 2006 changes were a pivot point in the platform’s history and in the broader Web 2.0 era. The News Feed established the algorithmic, activity-driven stream that would become the dominant interface model for all subsequent social media — Twitter’s timeline, Instagram’s feed, TikTok’s For You Page all derive from the News Feed’s core logic. Open registration converted Facebook from a walled student network into a service for everyone.
The episode also previewed a tension that would recur throughout Facebook’s history: the collision between aggressive product changes and user expectations of privacy. The 2006 revolt — and the company’s choice to retain the feature while adding controls — prefigured later controversies over data use, algorithmic amplification, and the feed’s influence on public discourse, reaching a systemic crisis with the Cambridge Analytica scandal in 2018 and ongoing regulatory attention through the 2020s.
The year’s developments fit within the participatory, user-generated turn that Time magazine recognized in December 2006 by naming “You” its Person of the Year, alongside the launch of Twitter and Google’s acquisition of YouTube.
