About Instagram
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, 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 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, 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.
Features of instagram
Users can upload photographs and short videos, follow other users' feeds,and geotag images with the name of a location.Users can set their account as "private", thereby requiring that they approve any new follower requests.Users can connect their Instagram account to other social networking sites, enabling them to share uploaded photos to those sites.In September 2011, a new version of the app included new and live filters, instant tilt–shift, high-resolution photographs, optional borders, one-click rotation, and an updated icon.Photos were initially restricted to a square, 1:1 aspect ratio; since August 2015, the app supports portrait and widescreen aspect ratios as well.Users could formerly view a map of a user's geotagged photos. The feature was removed in September 2016, citing low usage.
Since December 2016, posts can be "saved" into a private area of the app.The feature was updated in April 2017 to let users organize saved posts into named collections.Users can also "archive" their posts in a private storage area, out of visibility for the public and other users. The move was seen as a way to prevent users from deleting photos that don't garner a desired number of "likes" or are deemed boring, but also as a way to limit the "emergent behavior" of deleting photos, which deprives the service of content.In August, Instagram announced that it would start organizing comments into threads, letting users more easily interact with replies.
Since February 2017, up to ten pictures or videos can be included in a single post, with the content appearing as a swipeable carousel.The feature originally limited photos to the square format, but received an update in August to enable portrait and landscape photos instead.
In April 2018, Instagram launched its version of a portrait mode called "focus mode," which gently blurs the background of a photo or video while keeping the subject in focus when selected.In November, Instagram began to support Alt text to add descriptions of photos for the visually impaired. They are either generated automatically using object recognition (using existing Facebook technology) or manually specified by the uploader.
On March 1, 2021, Instagram launched a new feature named Instagram Live "Rooms" Let Four People Go Live Together.
In May 2021, Instagram announced a new accessibility feature for videos on Instagram Reels and Stories to allow creators to place closed captions on their content.
Hashtags
In January 2011, Instagram introduced hashtags to help users discover both photos and each other.[137][138] Instagram encourages users to make tags both specific and relevant, rather than tagging generic words like "photo", to make photographs stand out and to attract like-minded Instagram users.
Users on Instagram have created "trends" through hashtags. The trends deemed the most popular on the platform often highlight a specific day of the week to post the material on. Examples of popular trends include #SelfieSunday, in which users post a photo of their faces on Sundays; #MotivationMonday, in which users post motivational photos on Mondays; #TransformationTuesday, in which users post photos highlighting differences from the past to the present; #WomanCrushWednesday, in which users post photos of women they have a romantic interest in or view favorably, as well as its #ManCrushMonday counterpart centered on men; and #ThrowbackThursday, in which users post a photo from their past, highlighting a particular moment.
In December 2017, Instagram began to allow users to follow hashtags, which display relevant highlights of the topic in their feeds.
