The impact of Instagram’s new video product on Vine was felt almost immediately, but a new report paints a far scarier picture of Vine’s decline now that Instagram is looking to eat its lunch. Using Topsy’s analytics tool, Marketing Land ran a quick analysis of links to Instagram and links to Vine posted on Twitter during the 30-day period ending on June 26th. The results are pretty staggering, and quiteÂ disconcertingÂ for the Twitter-owned Vine app. According to Topsy, Vine videos shared on Twitter sat at about 2.5 million on June 19th, the day before Facebook added video-sharing to Instagram. That figure plummeted 40% on June 20th as video rolled out to Instagram users, and it continued declining to just 919,000 on June 26th. Meanwhile, a total of 1.49 million Instagram videos and images were shared on June 26th, according to Topsy’s data.
