The photo-and-video app Facebook bought for $1 billion in 2012 — now an estimated 3 billion users and about 44% of Meta's revenue — whose acquisition the U.S. government tried and failed to unwind in a 2020–2025 antitrust case.

Instagram is the photo-and-video social network Meta Platforms bought for about $1 billion in 2012 — a 13-person startup with 30 million users and no revenue plan (AllThingsD) — that has since grown to an estimated 3 billion monthly users and roughly 44% of Meta’s revenue (Business of Apps). In November 2025, a U.S. judge rejected the Federal Trade Commission’s bid to unwind that acquisition, ending a five-year antitrust fight (Associated Press).
Overview
Instagram began as Burbn, a location-sharing app built by engineer Mike Krieger and former Google programmer Kevin Systrom, which they pared to photo-sharing after a $500,000 seed round; filters — added because phone photos looked poor — became its signature (Business of Apps). It launched for iOS on October 6, 2010, with Android following in April 2012 (Business of Apps). It hit 1 billion monthly active users in June 2018 and an estimated 3 billion by the third quarter of 2025, making it the world’s third most popular social app (Business of Apps). India is its largest market with an estimated 481 million users, ahead of the United States at 182 million (Business of Apps). Instagram is owned by Meta Platforms, headquartered in Menlo Park, California, and led by CEO Adam Mosseri (Business of Apps). It absorbed rivals’ ideas — video in 2013 in the style of Vine, Stories in 2016 borrowed from Snapchat, and Reels as its answer to TikTok short-form video (Business of Apps).
The acquisition the government tried to undo
On April 9, 2012, Facebook announced it would buy Instagram for about $1 billion in cash and stock — its largest acquisition — when it had 13 employees and 30 million iPhone users (AllThingsD). Instagram had no revenue plan; monetization would be Facebook’s problem (AllThingsD). CEO Mark Zuckerberg promised to grow Instagram independently, calling it Facebook’s first acquisition of a product with so many users (AllThingsD). The stock component shrank the deal’s value to about $750 million after Facebook’s IPO dip (Associated Press). In 2020 the FTC sued, alleging a “buy-or-bury” strategy against emerging rivals (Associated Press). At the six-week trial in April–May 2025, Zuckerberg faced emails including his 2008 line “it is better to buy than compete” (Associated Press). On November 18, 2025, Judge James E. Boasberg ruled the FTC had not proved Meta currently holds a monopoly — accepting TikTok, now “center stage as Meta’s fiercest rival,” and YouTube as genuine competitors — so Meta kept Instagram (Associated Press).
The founders walked out; the app grew up
In September 2018, founders Kevin Systrom and Mike Krieger resigned, six years after the acquisition, amid reported clashes with Zuckerberg over its direction (PetaPixel). Systrom said they had grown “from 13 people to over a thousand” and wanted to “explore our curiosity and creativity again” (PetaPixel). Bloomberg reported frustration with Zuckerberg’s day-to-day involvement; the Wall Street Journal reported clashes over growth tactics and faster expansion (PetaPixel). Adam Mosseri now heads Instagram (TechCrunch). In June 2021 Mosseri declared, “We’re no longer a photo-sharing app” — users came “to be entertained” — citing “serious competition” from TikTok and YouTube, and pivoted the app toward full-screen, recommended video (Engadget). Instagram’s answer to TikTok, the short-form Reels format, is now described as TikTok’s largest competitor (Business of Apps). In July 2023 Instagram launched Threads, its text-based Twitter rival: 100 million signups in five days beat ChatGPT’s growth record, though it debuted without DMs, hashtags, or a Following feed (TechCrunch).
The teen-safety reckoning — and the money
On September 17, 2024, Meta moved every Instagram user under 18 into “Teen Accounts” — private by default, with messaging and tagging limited to accounts they follow, the most restrictive content settings, and parental permission required for under-16s to loosen anything (Reuters). The overhaul followed years of pressure: studies linking social media to youth depression and anxiety, hundreds of lawsuits from children and school districts, a 2023 suit by 33 U.S. states including California and New York, and Meta’s abandonment of a kids’ version of Instagram around 2021 (Reuters). Meanwhile the economics tell their own story: Instagram generated an estimated $86.3 billion in 2025 — about 44% of Meta’s total revenue, per Business of Apps — which means the 13-person company Facebook bought for $1 billion in 2012 now funds nearly half of its parent (Business of Apps). That inversion is precisely why the government spent five years trying to unwind the deal.

Frequently asked questions
Who founded Instagram? Kevin Systrom and Mike Krieger founded Instagram. They had built a location-sharing app called Burbn, raised a $500,000 seed round, then stripped it down to photo-sharing with filters — the feature that made phone photos worth sharing. The iOS app launched on October 6, 2010; Android followed in April 2012 (Business of Apps).
Why did Facebook buy Instagram? Facebook announced the $1 billion cash-and-stock acquisition on April 9, 2012, when Instagram had 13 employees, 30 million iPhone users, and no revenue plan. Mark Zuckerberg promised to grow it independently. The FTC later argued the deal was a “buy-or-bury” move against a rival; a judge rejected that case in November 2025 (AllThingsD; Associated Press).
Did the U.S. government try to separate Instagram from Meta? Yes. The Federal Trade Commission sued in 2020, arguing Meta maintained a monopoly partly through its 2012 Instagram acquisition. After the April–May 2025 trial, Judge James E. Boasberg ruled on November 18, 2025 that the FTC had not proved a current monopoly, citing TikTok and YouTube as competitors. Meta kept Instagram (Associated Press).
How does Instagram make money? Almost entirely from advertising. Business of Apps estimates Instagram generated $86.3 billion in 2025 — about 44% of Meta’s total revenue, a share that has risen every year since 2015. Revenue flows from ads across Feed, Stories, Reels, and shopping surfaces to its estimated 3 billion monthly users (Business of Apps).
Is Instagram still mainly a photo-sharing app? In June 2021, head of Instagram Adam Mosseri said the company was “no longer a photo-sharing app,” arguing users come “to be entertained” amid “serious competition” from TikTok and YouTube. Instagram pivoted to full-screen recommended video and built Reels into what Business of Apps calls TikTok’s largest competitor — though photos remain part of the app (Engadget; Business of Apps).
What this profile does not claim
- It does not state a precise current user count as Meta’s own figure; Meta reports Instagram-specific numbers only intermittently, so the figures here are dated third-party estimates.
- It does not present Instagram’s revenue as a Meta-disclosed segment result; the dollar amounts and revenue-share percentages are estimates, qualified wherever used.
- It does not resolve whether the acquisition’s post-IPO-dip value was $750 million (Associated Press) or $715 million (PetaPixel); the disagreement is recorded in the open items above.
- It does not claim to know whether the FTC will appeal the November 2025 ruling; that was unknown as of the research date.
- It does not claim any substantive relationship between Instagram and the film Ayla: The Daughter of War — the platform was merely the medium for one quoted statement by the film’s screenwriter, which does not meet this project’s direct-relationship test for linking.
