The first YouTube video to reach 1 billion views was PSY’s “Gangnam Style,” on December 21, 2012. Guinness World Records lists it as the “first video to receive one billion views on YouTube,” with 1,000,382,639 views as of that date, 159 days after it was uploaded. Guinness describes it as “the first video of any kind to receive 1 billion views online.” Before that, the most-viewed video on YouTube was Justin Bieber’s “Baby,” which “Gangnam Style” overtook in November 2012.
If you have seen other answers, you are not imagining it. Several different videos hold different “firsts,” and one famous story about “Gangnam Style” breaking YouTube is only half true. Here is how to tell them apart, and how YouTube actually counts a view today.
First YouTube video to reach 1 billion views: the official record
The cleanest answer comes from the body that certifies the record. Guinness World Records’ entry for the first video to receive one billion views (read September 25, 2026) states:
- Holder: PSY
- Date: December 21, 2012
- Views at the time: 1,000,382,639 on YouTube
- Time taken: 159 days after upload
Counting back 159 days from December 21 puts the upload in mid-July 2012. Guinness also notes that the video became the most-liked video on YouTube and had overtaken “Baby” as the most-viewed video online by November 2012.
Wikipedia’s list of the most-viewed YouTube videos agrees on December 21, 2012, for the 1 billion milestone and dates the moment “Gangnam Style” took the overall most-viewed title from “Baby” to November 24, 2012.
Why you have seen three different answers
Most wrong answers come from mixing up different records. They are easy to confuse because some of the same videos appear in several of them.
| Record | Video | Date | Source |
|---|---|---|---|
| First video to 1 billion views | “Gangnam Style,” PSY | December 21, 2012 | Guinness World Records; Wikipedia |
| Most-viewed video just before “Gangnam Style” | “Baby,” Justin Bieber | Held the title from July 15, 2010, to November 24, 2012 | Wikipedia |
| First video to 2 billion views | “Gangnam Style,” PSY | May 30, 2014 | Wikipedia |
| First video to 3, 4 and 5 billion views | “Despacito,” Luis Fonsi | August 4, 2017; October 11, 2017; April 5, 2018 | Wikipedia |
| First video to 10 billion views | “Baby Shark Dance,” Pinkfong | January 13, 2022 | Wikipedia |
So when someone says “Baby” was first, they usually mean it was the most-viewed video before “Gangnam Style.” When someone says “Baby Shark,” they usually mean the 10 billion milestone. Only “Gangnam Style” was first to a billion.
The most-viewed video before “Gangnam Style”
The billion-view record makes more sense against the history of YouTube’s “most-viewed” title. Wikipedia’s list records a string of earlier holders:
- 2005 to 2006: early holders included a Nike ad featuring Ronaldinho, and then “Evolution of Dance,” which took the title on May 19, 2006.
- 2008: the title changed hands among “Evolution of Dance,” an obscure clip called “Music Is My Hot Hot Sex,” which Wikipedia lists as the first video to pass 100 million views on March 11, 2008, and Avril Lavigne’s “Girlfriend.”
- October 25, 2009: “Charlie Bit My Finger” took the title, the last non-music video to hold it.
- April 14, 2010: Lady Gaga’s “Bad Romance.”
- July 15, 2010: Justin Bieber’s “Baby.”
- November 24, 2012: “Gangnam Style.”
Wikipedia makes a telling point: since “Bad Romance” in April 2010, every video to top the most-viewed list has been a music video. The billion-view record arrived as YouTube was becoming a default place to play music, in the same years that phones absorbed the job of dedicated music players, a shift our history of what happened to MP3 players traces.
Part of what made the billion-view milestone feel so big is that nothing had come close. Guinness notes that the video’s view count had passed the population of China by February 2013, which gave an easy way to picture the number.
Did “Gangnam Style” really break YouTube’s view counter?
This is the most garbled part of the story. The short answer: YouTube joked that it did, but nothing actually broke.
In early December 2014, YouTube posted on Google+ that “Gangnam Style” had passed the largest number its original counter could hold. Engadget reported on December 4, 2014, that the post said: “We never thought a video would be watched in numbers greater than a 32-bit integer [2,147,483,647 views], but that was before we met PSY.” YouTube added that it had upgraded to a 64-bit integer. ABC News in Australia reported on December 5, 2014, that the video had “more than 2.15 billion views” at the time.
The number itself is real computer science. A signed 32-bit integer tops out at 2,147,483,647, so any counter stored that way cannot go higher. A signed 64-bit integer allows over nine quintillion. (One Australian report described the new ceiling as “nine sextillion,” which overstates it by a factor of about a thousand.)
But the drama was a joke. Tech Times reported on December 6, 2014, that YouTube’s engineers had “anticipated the problem a few months ago” and upgraded the counter before the video ever reached the limit. A Google spokesperson told the outlet: “Nothing actually broke. There was never anything that actually went wrong. It’s just people having fun with the language.” Engadget noted that hovering over the counter on the video made the digits spin, an Easter egg YouTube added for the occasion.
So the accurate version is: “Gangnam Style” was the first video to approach the 32-bit ceiling, YouTube upgraded ahead of time, and then announced it with a joke that many outlets reported as a crash. The original Google+ post is no longer on the platform it was written for; our history of what happened to Google Plus covers how that network was shut down.
How YouTube counts a view in 2026
The billion-view record was counted under YouTube’s rules at the time. Those rules have just changed significantly, which matters when you compare old records with new ones.
YouTube’s own blog post of August 19, 2026 (read September 25, 2026) explains that from August 24, 2026, a view is counted “from the very first frame, whether that’s a Short appearing in the feed or a long-form video autoplaying on the Home page.” What used to count as a view, “clicking to watch or watching past the initial seconds,” is now called an “engaged view.” Thumbnail impressions without interaction still do not count as views.
YouTube Help adds that views are now counted “the moment a video starts to play across all formats, including Shorts, long-form videos (VOD), and live streams,” and that YouTube may “temporarily slow down, freeze, or change your metric count, and discard low-quality playbacks.” It gives watching the same video on several devices, or in several tabs at once, as examples of low-quality playbacks.
What this means for record comparisons:
- 2012 views and 2026 views are not the same unit. “Gangnam Style” reached a billion under a definition that required a click or a few seconds of watching. A 2026 view can count from the first frame.
- Engaged views are the closer comparison. YouTube’s post says the old definition now lives on as “engaged views,” so that is the fairer figure for comparing today’s videos with historic records.
- View counts are still filtered. YouTube continues to screen out views it judges not to come from real people, which is why counts sometimes pause or change.
How fast the billion-view club grew
“Gangnam Style” was alone for a while, but not for long. Wikipedia reports that ten videos had passed a billion views by October 2015 and that more than 400 had done so by 2024. By January 2022, “Baby Shark Dance” had passed 10 billion.
The milestones also show how quickly the leaders pulled ahead. The first billion took “Gangnam Style” 159 days, by Guinness’s count. The first video to 3 billion, “Despacito,” then reached 4 billion roughly two months later, going by the dates in Wikipedia’s list. A number that seemed impossible in 2012 became a regular milestone for major music releases within a few years.
That context is part of what makes the 2012 record interesting. It happened during a narrow window when YouTube was large enough for a single video to reach a billion views, but before billions became routine for the biggest releases.
