Instagram introduced Stories on August 2, 2016. The feature let users post photos and short videos that stack into a full-screen slideshow at the top of the app and disappear after 24 hours, and it quickly became one of the most influential formats in social media.
The short version: August 2, 2016
When Instagram rolled out Stories on August 2, 2016, the company was roughly six years old and already had more than 300 million daily users on its main feed. Stories was a distinct new surface: a row of circular profile icons across the top of the app that opened into tappable, full-screen photos and videos. Anything you posted there vanished after 24 hours and did not appear in your permanent grid.
The pitch was “imperfect sharing.” Instagram’s polished, heavily edited feed had made many users hesitant to post more than a few times a week. Stories removed that pressure. Because the content expired and lived outside the main grid, people felt free to share casual, in-the-moment clips they would never commit to their profile.
The Snapchat context and Kevin Systrom’s admission
There is no way to discuss the launch honestly without addressing the obvious: the format was Snapchat’s. Snapchat had introduced its own “Stories” feature in October 2013, built around the same core ideas of disappearing content and a chronological, full-screen slideshow of a user’s day. Instagram’s version, right down to the name, was clearly modeled on it.
Instagram’s then-CEO and co-founder Kevin Systrom did not dodge the comparison. Asked directly by TechCrunch whether Snapchat deserved credit for pioneering the format, he answered: “Totally. They deserve all the credit.” Systrom framed it as the normal way technology evolves, arguing that successful formats spread across platforms the same way feeds, hashtags, and @-usernames had before. He drew a line between wholesale copying of a product and identifying “what’s really awesome about a format” and adapting it to a different network and audience.
That candor was unusual for a major tech launch, and it shaped how the move was remembered. Instagram was not pretending to have invented anything. It was betting that it could execute the format better and at greater scale than the company that created it, thanks to a far larger existing user base.
How fast it grew
The bet paid off almost immediately. Instagram Stories reached 100 million daily active users within about two months of launch. It hit 200 million daily users by April 2017, which was already more than Snapchat’s entire app had at the time. The number climbed to 250 million by mid-2017, 300 million later that year, and 400 million by mid-2018.
In January 2019, Instagram confirmed that Stories had surpassed 500 million daily active users. That figure meant roughly half of Instagram’s total user base was opening Stories every single day. The growth also had a measurable effect on Snapchat, whose user-growth slowed sharply in the years after Instagram’s copy shipped. (Instagram has published Stories usage figures only intermittently since then, so the 500 million number from early 2019 remains the most reliable widely cited benchmark rather than a current count.)
How Stories changed Instagram
Stories did more than add a feature. It restructured how the app is used. The permanent grid became the place for your best, most curated work, while Stories became the high-frequency channel for everyday updates. For many users, Stories is now where the majority of their posting activity happens.
The format also reshaped Instagram’s business. Story ads, full-screen vertical placements between friends’ posts, became a major revenue driver and helped Instagram sell advertisers on vertical, mobile-first video years before it was standard. For creators and brands, the 24-hour clock encouraged near-daily posting, which increased time spent in the app and gave Instagram more inventory to monetize.
The feature evolution
Instagram spent the years after launch turning Stories from a simple slideshow into a dense toolkit. A few of the most consequential additions:
Highlights
Introduced in December 2017, Highlights let users save expired Stories into permanent, themed collections displayed on their profile below the bio. This softened the “disappears forever” rule and gave the format a lasting home, useful for everything from portfolios to product catalogs.
Interactive stickers: polls, questions, and quizzes
Instagram added the poll sticker in October 2017, followed by question stickers, emoji sliders, and quizzes. These turned a one-way broadcast into a two-way conversation and became a staple of how creators and brands drive engagement.
Close Friends
Launched in late 2018, Close Friends lets users share a Story with a hand-picked list rather than all followers. Marked with a green ring, it created a more private, selective layer inside a very public app and has since expanded to other parts of Instagram.
The relationship with Reels
Reels, Instagram’s short-form video product and its answer to TikTok, arrived in August 2020. Reels and Stories are often confused but serve different purposes: Stories are ephemeral, chronological, and aimed at your existing followers, while Reels are permanent, algorithmically distributed, and built to reach new audiences. In practice they complement each other, and Instagram frequently lets users cross-post between them.
Notes and the ephemeral mindset
The disappearing, low-stakes philosophy that Stories established has spread across Instagram. Notes, launched in December 2022, applies a similar idea to text: short status messages that appear at the top of the direct-messages inbox and vanish after 24 hours. It is not part of Stories itself, but it reflects how thoroughly the ephemeral format reshaped the company’s thinking about casual sharing.

Its impact on social media
The single most striking legacy of Instagram Stories is how completely the industry adopted the format it borrowed. After Instagram proved the model could scale, disappearing, full-screen Stories appeared across Facebook, WhatsApp, YouTube, LinkedIn, Twitter (as “Fleets,” later discontinued), and others. What Snapchat invented and Instagram popularized effectively became a default surface for social apps.
Stories also normalized a two-tier model of online identity: a curated permanent profile alongside a fast, casual, expiring feed. That split is now so common that most users never think about it. And commercially, Stories helped push the entire industry toward vertical, full-screen mobile video, the same format that later powered TikTok, Reels, and Shorts.
Conclusion
Instagram introduced Stories on August 2, 2016. It was an openly acknowledged copy of Snapchat’s format, one that Kevin Systrom said Snapchat deserved “all the credit” for. But the execution and scale were Instagram’s own, and within about two and a half years the feature reached more than 500 million daily users. Nearly a decade later, Stories has grown from a simple 24-hour slideshow into a core pillar of the app and a template that reshaped how nearly every major social platform works.
