Instagram

The social media platform has doubled its user base in two years.

Stop me if you think you’ve heard this one before: Facebook has released a Snapchat clone. The new standalone app offers ephemeral picture and video messaging, as well as the all-important AR lenses – sorry, “masks” – and is particularly targeted at users in emerging markets.

Instagram has introduced a feature that allows users to block abusive or offensive comments on photos.

Justin Bieber, the world’s sixth biggest Instagram user, has deleted his account and left the photo and video service.

Instagram on Tuesday launched a product designed to directly take on emerging rival Snapchat. The product, called "Stories" appears directly inside Instagram's app.

The photo-sharing app Instagram now has 550 million users, reaping the benefits from the growth of selfies and the propensity for celebrities such as Kim Kardashian to share images with a wider audience.

Is your Instagram feed still ordered oldest-to-newest? Then treasure your straightforward user experience because it is not going to last.

Facebook founder Mark Zuckerberg didn’t even begin to learn programming until he got a tutor at 11 years old – so he may have met his match in a 10-year-old Finnish schoolboy who has received a $10,000 bounty from Facebook after finding a vulnerability in Instagram’s code.

Forthcoming changes to Instagram’s algorithm, which will present photos out of chronological order, have thrown the photo-sharing app into chaos, with users asking their followers to “turn on notifications” so their updates aren’t lost to the new regime.
