Facebook-owned photo and video-sharing app Instagram announced new milestones yesterday. “We’re proud to announce that there are now more than 300 million Instagrammers. Over the past four years, what began as two friends with a dream has grown into a global community that shares more than 70 million photos and videos each day,” wrote CEO Kevin Systrom in a blog post. That’s bigger than Twitter, which had 284m active users last time it announced figures. Instagram’s growth is gathering pace too: it reached 100m users in February 2013, two and a half years after launching. Then 200m in March 2014, meaning it has taken just nine months to add another 100m active users since then. The new milestone was accompanied by the announcement of two new features: verified badges for celebrities and brands, and a crackdown on “spammy” accounts, which will be deleted from the service as it continues to court advertisers.
