Twitter

Twitter (/ˈtwɪtər/) is an online social networking service that enables users to send and read short 140-character messages called "tweets".

Registered users can read and post tweets, but those who are unregistered can only read them. Users access Twitter through the website interface, SMS or mobile device app. Twitter Inc. is based in San Francisco and has more than 25 offices around the world.

Twitter was created in March 2006 by Jack Dorsey, Evan Williams, Biz Stone, and Noah Glass and launched in July 2006. The service rapidly gained worldwide popularity, with more than 100 million users posting 340 million tweets a day in 2012. The service also handled 1.6 billion search queries per day. In 2013, Twitter was one of the ten most-visited websites and has been described as "the SMS of the Internet". As of May 2015, Twitter has more than 500 million users, out of which more than 332 million are active.

History

Creation and initial reaction

Twitter's origins lie in a "daylong brainstorming session" held by board members of the podcasting company Odeo. Jack Dorsey, then an undergraduate student at New York University, introduced the idea of an individual using an SMS service to communicate with a small group. The original project code name for the service was twttr, an idea that Williams later ascribed to Noah Glass, inspired by Flickr and the five-character length of American SMS short codes. The decision was also partly due to the fact that domain twitter.com was already in use, and it was six months after the launch of twttr that the crew purchased the domain and changed the name of the service to Twitter. The developers initially considered "10958" as a short code, but later changed it to "40404" for "ease of use and memorability". Work on the project started on March 21, 2006, when Dorsey published the first Twitter message at 9:50 PM Pacific Standard Time (PST): "just setting up my twttr". Dorsey has explained the origin of the "Twitter" title:

President of the United States

The President of the United States of America (POTUS) is the elected head of state and head of government of the United States. The president leads the executive branch of the federal government and is the commander-in-chief of the United States Armed Forces.

The President of the United States is considered one of the world's most powerful people, leading the world's only contemporary superpower. The role includes being the commander-in-chief of the world's most expensive military with the largest nuclear arsenal and leading the largest economy by real and nominal GDP. The office of the president holds significant hard and soft power both in the United States and abroad.

Article II of the U.S. Constitution vests the executive power of the United States in the president. The power includes execution of federal law, alongside the responsibility of appointing federal executive, diplomatic, regulatory and judicial officers, and concluding treaties with foreign powers with the advice and consent of the Senate. The president is further empowered to grant federal pardons and reprieves, and to convene and adjourn either or both houses of Congress under extraordinary circumstances. The president is largely responsible for dictating the legislative agenda of the party to which the president is enrolled. The president also directs the foreign and domestic policy of the United States. Since the founding of the United States, the power of the president and the federal government has grown substantially.

United States presidential election, 2016

The United States presidential election of 2016, scheduled for Tuesday, November 8, 2016, will be the 58th quadrennial U.S. presidential election. Voters will select presidential electors who in turn will elect a new president and vice president through the Electoral College. The term limit established in the Twenty-second Amendment to the United States Constitution prevents the incumbent President, Barack Obama, from being elected to a third term.

The series of presidential primary elections and caucuses is taking place between February 1 and June 2016, staggered among the 50 states, the District of Columbia and U.S. territories. This nominating process is also an indirect election, where voters cast ballots for a slate of delegates to a political party's nominating convention, who then in turn elect their party's presidential nominee.

Background

Article Two of the United States Constitution provides that for a person to be elected and serve as President of the United States, the individual must be a natural-born citizen of the United States, at least 35 years old, and a resident of the United States for a period of no less than 14 years. Candidates for the presidency typically seek the nomination of one of the various political parties of the United States, in which case each party devises a method (such as a primary election) to choose the candidate the party deems best suited to run for the position. The primary elections are usually indirect elections where voters cast ballots for a slate of party delegates pledged to a particular candidate. The party's delegates then officially nominate a candidate to run on the party's behalf. The general election in November is also an indirect election, where voters cast ballots for a slate of members of the Electoral College; these electors in turn directly elect the President and Vice President.
