Instagram

• 1. Introduction

  ›

  Instagram reached one billion registered users in June 2018 - a number that took Facebook four years longer to achieve. The platform launched for iOS in October 2010, created by Kevin Systrom and Brazilian software engineer Mike Krieger, and within two months it had already attracted one million users. Within a year, ten million. What began as a pivot from a failed check-in app called Burbn would become one of the most used social platforms on earth, bought by Facebook for approximately one billion dollars before it had generated a single dollar in profit. How did a photo-sharing app with a square-only image format grow into a platform hosting billions of photos, fueling advertising empires, reshaping teenage mental health, and drawing scrutiny from governments on multiple continents? The answers lie in a series of pivots, acquisitions, controversies, and design decisions that few could have predicted from a $500,000 seed round closed on the 5th of March 2010.

• 2. From Burbn to the First Post

  ›

  Systrom closed that seed round with Baseline Ventures and Andreessen Horowitz while still working on Burbn, a mobile check-in app with a heavy resemblance to Foursquare. Recognizing the similarity, Systrom and Krieger stripped the app back and focused on photo-sharing, which had already emerged as the most popular feature among their early users. They named the new product Instagram, a portmanteau of "instant camera" and "telegram." The first Instagram post was a photograph of South Beach Harbor at Pier 38. Mike Krieger posted it at 5:26 p.m. on the 16th of July 2010, nearly three months before the public launch. When the iOS app went live through the App Store on the 6th of October 2010, it was built around a single constraint: all images had to fit in a square 1:1 aspect ratio of 640 pixels, matching the display width of the iPhone at that time. That restriction shaped the platform's early aesthetic and set it apart from every other photo-sharing service. By February 2011, a Series A funding round had raised $7 million, valuing the company at around $20 million. The investors included Benchmark Capital, Jack Dorsey, Chris Sacca, and Adam D'Angelo.

• 3. The Facebook Acquisition

  ›

  On the 3rd of April 2012, Instagram released its Android app, and it was downloaded more than one million times in under a day. Six days later, on the 9th of April, Facebook announced it would buy Instagram for one billion dollars in cash and stock, with the stated intention of keeping the company independently managed. Mark Zuckerberg publicly committed to "building and growing Instagram independently." The deal attracted regulatory scrutiny on two continents. Britain's Office of Fair Trading approved it on the 14th of August 2012; the Federal Trade Commission closed its investigation on the 22nd of August. When the deal officially closed on the 6th of September 2012, the final price had changed: $300 million in cash and 23 million shares of stock. Commentators noted the contrast with the $35 million Yahoo! had paid for Flickr in 2005. According to Wired, Systrom personally netted $400 million from the transaction. That same April, Instagram raised an additional $50 million from venture capitalists at a valuation of $500 million - a round closed just weeks before the acquisition announcement. Joshua Kushner was the second-largest investor in that Series B, and his firm Thrive Capital doubled its money after the Facebook sale.

• 4. Building the Advertising Machine

  ›

  Emily White joined Instagram as Director of Business Operations in April 2013. In a September 2013 interview with The Wall Street Journal, she predicted the company would be ready to sell advertising by September 2014. White left for Snapchat in December 2013 before that moment arrived, and James Quarles took over as Global Head of Business and Brand Development in August 2014. The first image advertisements appeared in U.S. feeds on the 1st of November 2013. Video ads followed on the 30th of October 2014, nearly a year later. By February 2016, Instagram counted 200,000 advertisers. That figure more than doubled to 500,000 by September 2016, and reached one million by March 2017. The platform's move into shopping accelerated in April 2019, when Instagram added a "Checkout on Instagram" option allowing merchants to sell products directly inside the app. In June 2021, Instagram launched a native affiliate marketing tool; commission-enabled posts were labeled "Eligible for Commission," with launch partners including Sephora and MAC. In February 2023, Zuckerberg announced that Meta would start selling blue verified badges on Instagram and Facebook, turning a status symbol that had previously been granted by Instagram's own discretion into a paid product.

• 5. Stories, Reels, and the Snapchat Shadow

  ›

  Instagram Stories launched in August 2016, giving users a way to post photos and videos that expired after 24 hours. The media immediately noted the feature's resemblance to Snapchat. CEO Kevin Systrom did not deny the comparison. He told Recode that Instagram had been built on the day of its launch from combinations of Hipstamatic, Twitter, and Facebook features, and he argued that multiple car companies could coexist while serving different audiences. By January 2019, Stories was used by 500 million people daily. In October 2016, two months after launch, Stories had already reached 100 million active users - a pace that surpassed Snapchat's growth. Reels arrived in August 2020, initially launching in 50 countries including the United States, Canada, and the United Kingdom. The feature targeted TikTok directly and functioned similarly, letting users create short vertical videos set to existing sounds. By September 2022, Reels generated over 140 billion views daily, reaching 150 billion by November 2024. Despite Meta spending heavily on courting creators, user engagement in Reels continued to lag behind TikTok as of 2022. On the 26th of February 2025, a technical error caused violent and graphic content to surge into Reels feeds; Meta issued a public apology. A related video editing app called Edits, announced on the 19th of January 2025 as a response to U.S. government actions against TikTok and CapCut, officially launched for both iPhone and Android on the 21st of April 2025.

• 6. Mental Health and the Internal Research

  ›

  In 2021, The Wall Street Journal obtained and published internal Meta research that had been seen by company executives, including findings cited in connection with CEO Mark Zuckerberg in 2020. The leaked material drew on three qualitative studies: the first interviewed 15 monthly Californian Instagram users aged 13-21 with low body image and self-esteem; the second recruited 10 users for a five-day diary study; the third selected 7 participants from that diary group for in-depth interviews. None of the studies was designed as a randomized controlled trial. The research found that Instagram had negatively affected the body image of one in three teenagers. Among teen girls, 70% experienced negative social comparison; among teen boys, 40% did. The research concluded that Instagram had a higher impact on appearance comparison than either TikTok or Snapchat. Separately, 13% of British teen users with suicidal thoughts could trace those thoughts to Instagram use, compared to 6% of American teen users with suicidal thoughts. Instagram's response characterized the Journal's report as focusing on a limited set of findings in a negative light. Meta defended keeping the research confidential on the grounds that it promoted frank internal dialogue. In the wake of the backlash, Meta announced it had paused development of an Instagram product aimed at children. Ireland's Data Protection Commission later fined the company $402 million in September 2022 over how it handled the privacy data of minors. Dr. Anna Lembke, chief of Stanford University's dual diagnosis addiction clinic, has described the short-form video format as a powerful stimulus triggering dopamine surges akin to other addictive behaviors.

• 7. Censorship and Political Flashpoints

  ›

  On the 7th of January 2021, following the attack on the U.S. Capitol, Instagram banned then-President Donald Trump indefinitely. Zuckerberg stated that the risks of allowing Trump to continue using the service during that period were simply too great. The platform has faced persistent criticism over inconsistent moderation decisions affecting political speech. In January 2020, following the assassination of Qasem Soleimani, Instagram removed posts expressing support for the Iranian general, citing U.S. sanctions. In May 2021, journalists and human rights activists reported that Instagram removed content referencing the potential eviction of Palestinian families from Sheikh Jarrah in East Jerusalem. Instagram attributed the deletions to glitches. In October 2023, Instagram's automated translation system incorrectly interpreted Arabic text combined with the Palestinian flag emoji as the phrase "Palestinian terrorists are fighting for their freedom," mislabeling users' profile bios. Instagram apologized and attributed the error to a computerized translation system. The Iranian government had separately offered moderators bribes of up to $9,000 to delete specific accounts, with journalist Masih Alinejad named as a particular target. On the 2nd of August 2024, Turkey blocked Instagram entirely after the platform deleted posts from users offering condolences for the death of Hamas leader Ismail Haniyeh.

• 8. What Comes Next

  ›

  Krieger and Systrom announced their departure from Instagram on the 24th of September 2018, and Adam Mosseri was named head of the platform on the 1st of October. Their creation now supports 33 languages including English, Hindi, Spanish, French, Japanese, and Korean. A native iPadOS app finally arrived on the 3rd of September 2025, more than fifteen years after the original iOS launch - the iPad version had previously run the iPhone app without using the larger screen. In September 2025, Instagram began testing a Reels-first interface in India and South Korea, where the Reels page would become the default home tab. In February 2026, Meta announced a safety feature to alert parents if teenage children repeatedly search for suicide or self-harm content, part of an expansion of parental supervision tools tied to ongoing legal scrutiny. That same month, Meta scheduled an end to end-to-end encryption in Instagram direct messaging for May 2026, a change that privacy researchers warned would reduce message confidentiality. The platform that began with a single square photo of South Beach Harbor now hosts over 50 billion uploaded photos, a figure that crossed that threshold by June 2023.
