Instagram (sometimes known as IG, Insta, or the gramme) is a picture and video-sharing social networking website developed by Kevin Systrom and Mike Krieger in California, United States. Facebook bought the business in April 2012 for roughly US$1 billion in cash and shares, according to the company. Users may submit images and videos, which can then be altered with filters and grouped using hashtags and geotagging to create a personalized feed. Users may explore other users' material by categories and locations, as well as see stuff that is currently trending. Users may like pictures and follow other users in order to add their material to a personal feed, which is shown to them.
When Instagram first launched, it differentiated itself by only allowing material to be framed in a square (1:1) aspect ratio of 640 pixels, which corresponded to the width of the display on the iPhone at the time. In 2015, the resolution was increased to 1080 pixels, which alleviated the limitations. As part of its recent enhancements, Instagram has added messaging capabilities, the ability to include multiple images or videos in the same post, and a "stories" feature, which is similar to that of its main competitor Snapchat and allows users to post photos and videos to a sequential feed, with each post being accessible by others for a period of 24 hours. As of January 2019, the Stories feature was being utilized by 500 million people each day, according to Google.
Instagram was first released for iOS in October 2010 and quickly gained popularity, with one million registered users in two months, ten million in a year, and one billion as of June 2018. Instagram currently has around 100 million active users. It all started with an Android app, which was launched in April 2012, and was followed by a feature-limited desktop interface in November 2012, a Fire OS app in June 2014, and an app for Windows 10 later that year. It has been more than 40 billion pictures submitted by the end of October 2015. Even while it is lauded for its reach, Instagram has come under fire for a variety of reasons, most notably for policy and interface modifications, accusations of censorship, and unlawful or inappropriate material posted by members of the public.
As of June 2021, Cristiano Ronaldo, a Portuguese professional footballer, is the most followed individual on social media, with more than 300 million followers.
In the week of January 14, 2019, a picture of an egg uploaded by the account @world record egg broke the previous record of 18 million likes set by a Kylie Jenner post. The account was established with the express aim of breaking the previous record of 18 million likes. The image has received more than 55 million likes as of this writing. The second most popular picture is a photograph of Ariana Grande and her husband Dalton Gomez taken during their wedding. Instagram rose to become the fourth most downloaded smartphone application of the decade of the 2010s.
