Twitter's darling Vine, the startup it purchased in October 2012, allows users to shoot and share six second videos, but is quickly being eclipsed by Facebook's Instagram, which added a video sharing feature a few weeks ago.
Instagram, in addition to its popular photo features, now allows users to share 15 second video clips, more than double the the length that Vine allows.
And, according to a new report from BGR, the news hasn't been pretty for Vine.
According to Topsy, Vine videos shared on Twitter was 2.5 million on 19 June, the day before Facebook added video-sharing to Instagram.
That figure fell a massive 40% on 20 June as video rolled out to Instagram users, and it continued declining to just 919,000 on 26 June.
At the same time, a total of 1.49 million Instagram videos and images were shared on 26 June, according to Topsy’s data.
Meanwhile, as Ubergizmo is reporting, Vine was the No.3 free iPhone app prior to the release of Video on Instagram. It held the top spot as recently as 13 June, and on 7 July it was down in No.16. Similar trends have been noticed in the UK and other European markets.
In the UK, Vine app slid down from its No.7 spot to No.21 on 7 July, in Switzerland it dropped to No.23. It's the same in Latin American markets as well, with the app plunging download from No.16 to No.86 in Brazil.
Can Twitter think of a new killer feature for its quickly dying Vine, or will it simply wither into oblivion?
