Explore the evolution of vertical video and its impact on social media platforms, driven by TikTok's success and the subsequent adaptations by Instagram and YouTube.

For a while, every social and media platform had its own identity. YouTube was for clips of TV shows and movies, and the home of so many members of a burgeoning creator community. Instagram was mostly pictures. Netflix was trying to be the on-demand HBO. Facebook was about friends. Twitter was about news. Snapchat was a messaging app.
All these apps did have one important thing in common, though: They were growing up alongside the smartphone. Billions of new people were coming online for the first time, and they began to make content that made sense for the tall, skinny new devices in their hands. Selfies were a vertical art form, both because the photos filled the screen better and because it was just easier to hold the phone and take the photo that way. Some resisted the idea of vertical video for years â theyâd argue that our eyes are meant to scan horizontally rather than vertically, and that vertical video looked bad on widescreen laptops. But ultimately phones won, and we hold our phones upright, so our phone experiences turned upright. That includes entertainment.
As has been true so many times, Snap figured this out before anyone. It launched Stories in late 2013 as a slightly more relaxed way to see what your friends are up to. CEO Evan Spiegel called it a âtotally new way to share your day with friends â or everyone.â It took off in a massive way, and by the middle of 2014 was the most popular feature on Snapchat. Thatâs the kind of virality that Mark Zuckerberg tends to notice, and by August of 2016, the feature had been copied more or less exactly into Instagram. Kevin Systrom, then the CEO of Instagram, said of Spiegel and Snapchat that âthey deserve all the creditâ for Stories. The implication? That this was no longer a proprietary feature of a single social network; it was just in the air. Stories were for everyone. They started showing up on LinkedIn, Tinder, Medium, and so many other places.
Stories werenât always video, but as cameras and upload speeds improved, video became the dominant medium in many ephemeral spaces. And video stories had two semi-magical properties: They were perfectly suited to endless, mindless scrolling, and they made it really easy to integrate ads. Only a few months after turning on Stories in Instagram, by which point half the platformâs users were already using Stories, Facebook began flooding ads into the product. The semi-randomness of Stories made ads actually seem less intrusive â youâd see a photo of a dog, a video of a hike, an ad for jeans, your friendâs makeup routine, brunch pics, an ad for blush. Video ads felt more premium, took up the whole screen, and were thus far more lucrative for the social platforms.
With apologies to the short, brilliant life of Vine, the six-second video platform that helped invent so much about the video-first social network, it wasnât until TikTok took off that things really turned again. The platform launched in the US in 2018, but had been popular for a few years in China as Douyin and elsewhere as Musical.ly. TikTok combined the vertical-first format of Stories with the permanence of YouTube, but it also made video easier than ever. It had filters like Instagram and Snapchat, but also supplied a steady stream of video ideas through the platformâs many trends, offered access to music and sound effects, and made it easy to stitch or duet a video.
By defaulting to the purely algorithmic For You page, TikTok also freed creators from caring about curating their profile or worrying about posting too much â you could just pump out videos and trust the algorithm to deliver them. And so thatâs what people did. Pretty quickly, TikTok became one of the fastest growing apps on the planet, and its daily usage numbers became the envy of the industry. Instagram may have had more users, but TikTok users spent far more time TikToking.
When TikTok became a phenomenon, just about everyone jumped on the vertical video bandwagon. Reels launched in 2020 and became a core feature of both Instagram and Facebook; YouTube created Shorts a year later. By the end of 2021, Twitter had both launched and killed a similar feature called Fleets. By this point, this kind of full-screen, vertical-scrolling video was part of the lingua franca of the smartphone. At the same time, in a search for ever more engagement, these platforms were learning another lesson from TikTok: to stop relying on your friends to post interesting content, and instead to show you whatever the algorithm thinks you might like. Social networks were gone, replaced by social media â entertainment with a comments section.
Short-form, vertical video has effectively won the internet. Business is booming, and viewers show no sign of tuning out. Meta said in 2024 that Instagram users were spending more than half their time in Reels, and said in 2025 the feature was turning into a $50 billion annual business across Metaâs apps. About 63 percent of young adults and teens are on TikTok, per Pew Research Center, and one in five teens reported being on the app âalmost constantly.â YouTube reported 200 billion daily views of Shorts at the end of 2025, and said that Shorts earned more money per watch hour than standard YouTube videos.
The last three or four years have been about relentless standardization in social media. The pace with which these products copy each other, and regress back toward parity, has been absolutely astonishing. First, Shorts and Reels both aped TikTokâs design, its duetting and stitching, and its close relationship with sounds and music. Then they bought into TikTokâs idea of prioritizing content over connection â followers are dead, long live the algorithm. TikTok pushed hard into shopping, then suddenly Reels and Shorts became a lot more shoppable. YouTube began to grow on TVs, and suddenly TikTok and Instagram started investing in its own TV apps. Videos got longer and longer across platforms, to allow more ads. All the apps got really into livestreaming for a while. And micro dramas. Theyâve relentlessly copied each other on big things like letting users control their algorithm, and small things like Clear Mode.
As the social platforms spin endlessly around each other, theyâve gotten some surprising company. Company after company started to notice their content floating around social media platforms, often in dubiously legal ways, and tried to take some of the watch time for themselves. Spotify decided it, too, wanted to be a video service, and built a vertical-scrolling feed for users to explore. Disney built a TikTok clone for ESPN and another for Disney Plus, both called Verts. Netflix, Prime Video, and Paramount Plus all called their clones Clips.
There are two reasons for the ongoing onslaught of short-form vertical video: time spent and advertising. The endlessly scrolling video feed turns out to be one of the most engrossing forms of entertainment ever devised (to the point that it has become a regulatory problem for the social platforms), and in a relentless competition for eyeballs and attention, it has become everyoneâs best idea. In 2024, when Meta switched its default video player to a vertical-first layout across all platforms, the race was officially won.
