Usually when new features are being tested, it's done in more mature established markets (e.g. USA, UK, India, etc.). This discovery made by me showed up for an account in Qatar, and the news started to spread wildly when Matt published it attributing the source to me.

This new discovery was made when I was uploading a video to YouTube, and then tipped off Matt Navarra about it. Got picked up by the following publications.
Turns out that certain publications started covering it but the content of their wrote up hints that they were briefed by YouTube under strict embargo. This is evident from The Verge publishing the same news not referencing the tweet that came out before their story.
Even 9to5Google referenced the tweet by linking to it, but it seems they also discovered it before but didn't publicize it. It's likely that the feature was scheduled to roll out soon.
As TikTok's popularity was growing, I was casually browsing through the app when I stumbled upon this new addition that would apply to Businesses.

Being a frequent Pinterest user, I stumbled upon this new discovery on my Android device and didn't even see it on the iOS version.
Got picked up by a social media publication, only to be officially confirmed by Pinterest that it's rolling out to creators.
