Instagram is a mobile, desktop, and Internet-based photo-sharing application and service that allows users to share pictures and videos either publicly, or privately to pre-approved followers.It was created by Kevin Systrom and Mike Krieger, and launched in October 2010 as a free mobile app exclusively for the i OS operating system.
As Krieger reasoned, Burbn became too similar to Foursquare, and both realized that it had gone too far.
Burbn was then pivoted to become more focused on photo-sharing.
As Instagram has grown, it's become harder to keep up with all the photos and videos people share.
This means you often don't see the posts you might care about the most.
Announced in March 2016 and taking place in June, Instagram switched from a strictly chronological oldest-to-newest news feed to a new, algorithm-based feed.
The change received "widespread outcry" following Instagram's March announcement, but Instagram stated that the feature would help users discover lost posts, writing that "You may be surprised to learn that people miss on average 70 percent of their feeds.The popularity of Instagram has resulted in widespread community engagement, including dedicated "trends", in which users post specific types of photos on specific days of the week with a hashtag representing a common theme.Instagram has received positive reviews for its i OS app, and it has been named "one of the most influential social networks in the world".The Android app has received two major exclusive updates.The first, introduced in March 2014, cut the size of the app by half and added significant improvements to performance and responsiveness on a wide variety of Android devices.However, the company has been the subject of criticism, most notably for policy and interface changes, allegations of censorship, and illegal or improper content uploaded by users.
