A president is a leader of an organization, company, club, trade union, university, or country.

Etymologically, a president is one who presides, who sits in leadership (from Latin pre- "before" + sedere "to sit"; giving the term praeses). Originally, the term referred to the presiding officer of a ceremony or meeting (i.e., chairman), but today it most commonly refers to an official. Among other things, "President" today is a common title for the heads of state of most republics, whether popularly elected, chosen by the legislature or by a special electoral college.

Presidents in countries with a democratic or representative form of government are usually elected for a specified period of time and in some cases may be re-elected by the same process by which they are appointed, i.e. in many nations, periodic popular elections. The powers vested in such presidents vary considerably. Some presidencies, such as that of Ireland, are largely ceremonial, whereas other systems vest the President with substantive powers such as the appointment and dismissal of Prime Ministers or cabinets, the power to declare war, and powers of veto on legislation. In many nations the President is also the Commander-in-Chief of the nation's armed forces, though once again this can range from a ceremonial role to one with considerable authority.

Elizabeth Woolridge Grant (born June 21, 1986), better known by her stage name Lana Del Rey, is an American singer-songwriter. Raised in upstate New York, Del Rey moved to New York City at age eighteen, where she attended college and began writing music and performing in clubs.

In 2008, Del Rey contracted with an independent label and recorded a self-titled debut album which was briefly available on iTunes in 2010; Del Rey ultimately bought back the rights to the album and it was withdrawn soon after.

In June 2011, she released the song "Video Games" on the Internet, accompanied by a self-made music video that went viral in the following months. The song was later released as a single in October, leading up to Del Rey's major-label debut album, Born to Die, which was released on January 31, 2012 through Interscope Records. Born to Die debuted at number one in seven countries, including the United Kingdom and Australia. The album has spawned two worldwide top 10 hits: "Video Games" and "Born to Die".

Steven Paul "Steve" Jobs (/ˈdʒɒbz/; February 24, 1955 – October 5, 2011) was an American businessman, designer and inventor. He is best known as the co-founder, chairman, and chief executive officer of Apple Inc. Through Apple, he was widely recognized as a charismatic pioneer of the personal computer revolution and for his influential career in the computer and consumer electronics fields. Jobs also co-founded and served as chief executive of Pixar Animation Studios; he became a member of the board of directors of The Walt Disney Company in 2006, when Disney acquired Pixar.

In the late 1970s, Apple co-founder Steve Wozniak engineered one of the first commercially successful lines of personal computers, the Apple II series. Jobs was among the first to see the commercial potential of Xerox PARC's mouse-driven graphical user interface, which led to the creation of the Apple Lisa and, one year later, the Macintosh. During this period he also led efforts that would begin the desktop publishing revolution, notably through the introduction of the LaserWriter and the associated PageMaker software.
