Twitter is an American microblogging and social networking service on which users post and interact with messages known as “tweets”. Registered users can post, like and retweet tweets, but unregistered users can only read them. Users access Twitter through its website interface or its mobile-device application software (“app”), though the service could also be accessed via SMS before April 2020.[13] Twitter, Inc. is based in San FranciscoCalifornia, and has more than 25 offices around the world.[14] Tweets were originally restricted to 140 characters, but was doubled to 280 for non-CJK languages in November 2017.[15] Audio and video tweets remain limited to 140 seconds for most accounts.

Twitter was created by Jack DorseyNoah GlassBiz Stone, and Evan Williams in March 2006 and launched in July of that year. By 2012, more than 100 million users posted 340 million tweets a day,[16] and the service handled an average of 1.6 billion search queries per day.[17][18][19] In 2013, it was one of the ten most-visited websites and has been described as “the SMS of the Internet”.[20] As of Q1 2019, Twitter had more than 330 million monthly active users.[10] Twitter is a some-to-many microblogging service, given that the vast majority of tweets are written by a small minority of users.[21][22]

Mark Zuckerberg (b. 1984)

“Facebook, the 800-pound gorilla of the social networking world, is one of the most significant communications platforms of the modern era. While the site was not the first online service that enabled people to exchange information about themselves or publicly promote their interests, it was the service that took the phenomenon global. Facebook raised public awareness about what constituted “social networking” and brought into focus how a simple piece of software could enable the everyday person to have a voice disproportionate to his or her economic position, geographic location, or access to sources of community organization and influence—a voice bounded only by the strength of what he or she had to say.

Facebook also served as a widespread wake-up call to traditional media outlets that their business models were ripe for disruption, as the mass media’s audience flipped and went from being consumers of media to creators. Now suddenly people were their own storytellers, editors, publishers, neighborhood leaders, or global trailblazers with a platform for instantaneous projection of information around the world.

Facebook was founded in 2004 by Mark Zuckerberg and fellow Harvard students who developed a centralized website to connect students across the university. The early roots of the Facebook site are generally believed to have originated with Zuckerberg’s short-lived “FaceMash” site, which gamified the choice of who was more attractive among pairs of people. The launch of “TheFacebook,” as it was first called, demonstrated that there was an unfulfilled desire to connect with and learn about other people—at least among the Harvard student body. Along the way there were various legal challenges and allegations of idea theft, including a lawsuit by two brothers named Cameron and Tyler Winklevoss, who ended up with a settlement worth $65 million—chump change, compared to Facebook’s 2017 market value of more than $500 billion.

Facebook quickly expanded beyond Harvard and opened to other universities, eventually turning into a business that was inclusive of anyone who wanted to join. In March 2017, the site had 1.94 billion monthly active user accounts.”
