Instagram is a social media[3] platform, initially released in 2010 by founders Kevin Systrom and Mike Krieger. It started as a check-in application named Burbn but later pivoted to a photo-sharing app, leading to the name Instagram. The platform is widely recognized for its photo and video sharing capabilities, complemented by features like hashtags, stories, and direct messaging. It has undergone significant growth and evolution over the years, expanding to multiple operating systems and continuously adding new tools and features. These include IGTV[6], Reels, and live streaming enhancements, aiming to enhance user experience[2]. Instagram also focuses on user safety, implementing child safety policies, and privacy[5] measures. It has become a key player in digital marketing[1], with advertising[4] initiatives and influencer engagement strategies.
Instagram is a photo and video sharing social networking service owned by Meta Platforms. It allows users to upload media that can be edited with filters, be organized by hashtags, and be associated with a location via geographical tagging. Posts can be shared publicly or with preapproved followers. Users can browse other users' content by tags and locations, view trending content, like photos, and follow other users to add their content to a personal feed. A Meta-operated image-centric social media platform, it is available on iOS, Android, Windows 10, and the web. Users can take photos and edit them using built-in filters and other tools, then share them on other social media platforms like Facebook. It supports 32 languages including English, Spanish, French, Korean, and Japanese.

Instagram was originally distinguished by allowing content to be framed only in a square (1:1) aspect ratio of 640 pixels to match the display width of the iPhone at the time. In 2015, this restriction was eased with an increase to 1080 pixels. It also added messaging features, the ability to include multiple images or videos in a single post, and a Stories feature—similar to its main competitor Snapchat—which allowed users to post their content to a sequential feed, with each post accessible to others for 24 hours. As of January 2019, Stories is used by 500 million people daily.
Originally launched for iOS in October 2010 by Kevin Systrom and Mike Krieger, Instagram rapidly gained popularity, with one million registered users in two months, 10 million in a year, and 1 billion by June 2018. In April 2012, Facebook Inc. acquired the service for approximately US$1 billion in cash and stock. The Android version of Instagram was released in April 2012, followed by a feature-limited desktop interface in November 2012, a Fire OS app in June 2014, and an app for Windows 10 in October 2016. As of October 2015[update], over 40 billion photos had been uploaded. Although often admired for its success and influence, Instagram has also been criticized for negatively affecting teens' mental health, its policy and interface changes, its alleged censorship, and illegal and inappropriate content uploaded by users.
