Greater Iran (in Persian: ایرانِ بُزُرگ‎ Irān-e Bozorg, or ایران زَمین Irānzamīn "Iranian soil" or ایران شهر Irānshahr "The Land of Iran") refers to the regions of South, West, and Central Asia that have significant Iranian cultural influence and have historically been ruled by Iranian peoples. It roughly corresponds to the territory on the Iranian plateau and its bordering plains, stretching from Iraq, the Caucasus, and Turkey in the west, to the Indus River of Pakistan in the east. It is also referred to as Greater Persia, while the Encyclopædia Iranica uses the term Iranian Cultural Continent.

The term 'Iran' is not limited to the modern state, more or less equivalent to western Iran. Iran includes all the political boundaries ruled by the Iranian including Mesopotamia and usually Armenia and Transcaucasia. In a sense the concept of Greater Iran, starts from the history that originated with the first Persian Empire or the Achaemenid Empire in Persis (Fars), and in fact is synonymous with history of Iran in many aspects. Persia lost many of its territories gained under the Safavid dynasty, including Iraq to the Ottomans (via Treaty of Amasya in 1555 and Treaty of Zuhab in 1639), Afghanistan to the British (via Treaty of Paris in 1857 and MacMahon Arbitration in 1905), and its Caucasus territories to Russia in the 18th and 19th centuries. The Treaty of Gulistan in 1813 resulted in Persia ceding Armenia, Azerbaijan, and eastern Georgia to Russia. The Turkmanchey Treaty of 1828, after the Russo-Persian wars permanently severed the Caucasian provinces from Iran and settled the modern boundary along the Aras River.

Iran (ⁱ/ɪˈrɑːn/ or /aɪˈræn/;Persian: ایران‎ [ʔiˈɾɒn] ( listen)), officially the Islamic Republic of Iran (Persian: جمهوری اسلامی ایران‎ Jomhuri-ye Eslāmi-ye Irān), is a country in Southern and Western Asia. The name "Iran", which in Persian means "Land of the Aryans", has been in use natively since the Sassanian era. It came into use internationally in 1935, before which the country was known to the Western world as Persia ( /ˈpɜrʒə/ or /ˈpɜrʃə/). Both "Persia" and "Iran" are used interchangeably in cultural contexts; however, "Iran" is the name used officially in political contexts.

The 18th-largest country in the world in terms of area at 1,648,195 km² (636,372 sq mi), Iran has a population of around 79 million. It is a country of particular geopolitical significance owing to its location in the Middle East and central Eurasia. Iran is bordered on the north by Armenia, Azerbaijan and Turkmenistan. As Iran is a littoral state of the Caspian Sea, which is an inland sea, Kazakhstan and Russia are also Iran's direct neighbors to the north. Iran is bordered on the east by Afghanistan and Pakistan, on the south by the Persian Gulf and the Gulf of Oman, on the west by Iraq and on the northwest by Turkey. Tehran is the capital, the country's largest city and the political, cultural, commercial and industrial center of the nation. Iran is a regional power, and holds an important position in international energy security and world economy as a result of its large reserves of petroleum and natural gas. Iran has the second largest proven natural gas reserves in the world and the fourth largest proven petroleum reserves.

The Iranian peoples (Iranic peoples) are an Indo-European ethnic-linguistic group that comprise the speakers of Iranian languages, a major branch of the Indo-European language family, as such forming a branch of the Indo-European-speaking peoples. Their historical areas of settlement were on the Iranian plateau, and comprised most of Iran and certain areas of Central Asia such as Tajikistan and Uzbekistan and most of Afghanistan, some parts of western Pakistan, northern Iraq and eastern Turkey, and scattered parts of the Caucasus Mountains. Their current distribution spreads across the Iranian plateau, and stretches from Pakistan's Indus River in the east to eastern Turkey in the west, and from Central Asia and the Caucasus in the north to the Persian Gulf in the south – a region that is sometimes called the Iranian cultural continent, or Greater Persia by scholars, and represents the extent of the Iranian languages and influence of the Persian People, through the geopolitical reach of the Persian empire.

Jon Stewart (born Jonathan Stuart Leibowitz; November 28, 1962) is an American political satirist, writer, television host, actor, media critic and stand-up comedian. He is widely known as host of The Daily Show, a satirical news program that airs on Comedy Central.

Stewart started as a stand-up comedian, but branched into television as host of Short Attention Span Theater for Comedy Central. He went on to host his own show on MTV, called The Jon Stewart Show, and then hosted another show on MTV called You Wrote It, You Watch It. He has also had several film roles as an actor. Stewart became the host of The Daily Show on Comedy Central in early 1999. He is also a writer and co-executive-producer of the show. After Stewart joined, The Daily Show steadily gained popularity and critical acclaim, resulting in his sixteen Emmy Awards.

Stewart has gained acclaim as an acerbic, satirical critic of personality-driven media shows, in particular those of the US media networks such as CNN, Fox News Channel, and MSNBC. Critics say Stewart benefits from a double standard: he critiques other news shows from the safe, removed position of his "fake news" desk. Stewart agrees, saying that neither his show nor his channel purports to be anything other than satire and comedy. In spite of its self-professed entertainment mandate, The Daily Show has been nominated for news and journalism awards. Stewart hosted the 78th and 80th Academy Awards. He is the co-author of America (The Book): A Citizen's Guide to Democracy Inaction, which was one of the best-selling books in the U.S. in 2004 and Earth (The Book): A Visitor's Guide to the Human Race released in 2010.
