What are the most used socials today?
There is Instagram, a US social networking service that allows users to take photos, apply filters and share them over the Internet. In 2012, Facebook bought it for a billion dollars. Instagram was originally distinct to only allow 1: 1 format images for the iPhone’s display width at the time. These restrictions were eased in 2015, with an increase to 1080 pixels. The service also added messaging functionality, the ability to include multiple images or videos in a single post, as well as “Stories,” similar to its main competitor Snapchat, which allows users to post photos and videos to a sequential feed, with each post accessible by others for 24 hours. As of January 2019, the Stories feature is used daily by 500 million users.
Facebook is a US social media and social network, launched for commercial purposes on February 4, 2004, owned and operated by the company Facebook Inc., and based on a web 2.0 platform written in various programming languages (initially PHP, then Hack). It is available in over 100 languages (in Italian since May 14, 2008); in June 2017, it reached 2.23 billion monthly active users, and was ranked as the number one social networking service by number of active users. Its name is inspired by a list with names and photographs of students, which some US universities distribute at the beginning of the academic year to help members socialize with each other.
Finally, WhatsApp (formally WhatsApp Messenger) is a US centralized instant messaging computer application created in 2009 by WhatsApp Inc., part of the Facebook Inc. group since February 19, 2014. Originally designed for use on a mobile device, a version has also been developed for desktop computer; the service requires users to provide a standard mobile phone number. Users can exchange text messages, images, video and audio files, as well as location information, documents and contact information between two people or in groups. At first, users could only communicate with others individually or in groups of individual users.
