Instagram launched a video service two months ago, and early analysis suggested the new video sharing tool has had a big effect on Twitter's Vine service.

A week after Instagram added video recording to its popular app, there was a dramatic decrease in the number of Vine shares on Twitter. 

We can use the free analytics tool from Topsy to compare how many times Twitter users have shared links versus links. The chart demonstrates the quick decline in Vine shares, which went into a nosedive on June 20, the day of Instagram's announcement. Topsy shows there were almost 2.5 million Vine links shared on June 19, then a little more than 1.5 million on the 20th — a drop of almost 40 percent in one day.



Topsy says its figures include retweets and links but not spam.

"Instagram hasn't actually seen a huge uptick in Twitter sharing since its video launch," wrote Matt McGee, editor of Marketing Land.

"The number of shares over the past few days is similar to early and mid-June. But Vine sharing is way down in the last week."

Twitter launched its video-sharing platform in January 2013. Users are able to upload and share six-second long clips which play in a loop.

Videos shared via Facebook-owned Instagram can be up to 15 seconds long and filters can be added to change the colouring.

Vine sharing peaked after Android release

The chart looks pretty bad for Vine, but after the Vine app debuted on Android, the share count looked very different on Topsy, with the six-second videos being shared more frequently than Instagram's filtered videos just a few weeks prior to the Instagram video launch.



The positive buzz Vine enjoyed after adding Android was largely nullified by Instagram’s news, since getting a whole new feature set is more exciting than expanding to a different operating system. And Instagram’s esteemed place in the social network word gives it an obvious leg up over Vine, which is still relatively new and working toward establishing itself.

There has been a lot of discussion in the past weeks about how the Vine usage completely collapsed. However, Kate Knibbs from Digital Trends offers a more balanced interpretation and interesting discussion using more comprehensive data from the Topsy service.
