Instagram revealed this week that it now has 1 billion monthly active users, up from the 800 million reported in September 2017.

This increase in monthly users makes Instagram the fastest growing social network at the moment — by a considerably margin.

While Facebook has more overall users, its growth in monthly users has stalled to just 3.14 percent. Snapchat is growing even slower, at a rate of 2.13 percent.

Instagram, on the other hand, is growing nearly 5 percent from quarter to quarter.

Ironically, Instagram’s continued growth could partially be attributed to copying features from Snapchat, such as stories and filters.

Stories have become wildly popular on Instagram, and the amount of people publishing stories has eclipsed Snapchat’s entire userbase.

Another potential factor contributing to Instagram’s growth is Facebook’s waning popularity with younger demographics. Teens are flocking toward Instagram and using Facebook less often.

I would be remiss not to mention Snapchat’s redesign, which has been poorly received by both users and critics.

While others stumble Instagram continues to succeed, making it the one of the most interesting social networks to keep an eye on right now.
