The Tonight Show is an American late-night talk show broadcast from the NBC Studios in Rockefeller Center in New York City, the show's original location, airing on NBC since 1954. The series has been hosted by six comedians: Steve Allen, Jack Paar, Johnny Carson, Jay Leno, on two occasions, Conan O'Brien, Jimmy Fallon, the series has had several recurring guest hosts including Ernie Kovacs during the Steve Allen era and Joan Rivers, Garry Shandling, Jay Leno during Johnny Carson's stewardship, although the practice has been abandoned since Carson's departure, with hosts preferring reruns to showcasing potential rivals; the Tonight Show is the world's longest-running talk show and the longest-running scheduled entertainment program in the United States. It Meet the Press. Over the course of more than 60 years, The Tonight Show has undergone only minor title changes, it aired under the name Tonight for several of its early years, as well as Tonight Starring Jack Paar and The Jack Paar Show due to the runaway popularity of its host settling permanently on The Tonight Show after Carson began his tenure in 1962, albeit with the host's name always included in the title.

Beginning with Carson's debut episode, network programmers and the show's announcers would refer to the show by including the name of the host. In 1957, the show tried a more news-style format, it has otherwise adhered to the talk show format honed further by Paar. Carson is the longest-serving host to date; the Tonight Show Starring Johnny Carson aired for 30 seasons between October 1962 and May 1992. Leno, has the record of having hosted the greatest number of total televised episodes. Leno's record accounts for the fact that unlike Carson, Leno never used guest hosts on The Tonight Show with Jay Leno and produced new shows five days a week. Leaving out Leno's five years as permanent guest host, Leno hosted 119 more episodes as full-time host than Carson. During Carson's first four years, the show ran for 105 minutes and was reduced to ninety minutes in early 1967 when Carson stopped appearing for the first 15 minutes because most affiliates were carrying their local news during that time slot as they expanded to half an hour.

During Carson's 1980 contract negotiations, the show was shortened to sixty minutes beginning that September, where it has remained since. NBC broadcast The Best of Carson which were repeats of some of Carson's popular older albeit recent shows. Prior to the debut of Saturday Night Live in October 1975, NBC aired The Best of Carson on Saturday nights at 11:30 pm. Outside of its brief run as a news show in 1957, Conan O'Brien is the shortest-serving host. O'Brien hosted 146 episodes over the course of less than eight months before Leno was brought back as host, where he served for four additional years. Current host Fallon took the helm on February 17, 2014. Fallon had hosted Late Night with Jimmy Fallon, before Late Night he was a popular member of the cast of Saturday Night Live, co-hosting the "Weekend Update" with Tina Fey as well as performing sketches. From 1950 to 1951 NBC aired Broadway Open House, a nightly variety show hosted by comic Jerry Lester, it was not a success. A spin-off, Dagmar's Canteen, aired the following season on Saturday nights.

The format of The Tonight Show can be traced to a nightly 40-minute local program in New York, hosted by Allen and titled The Knickerbocker Beer Show. It was retitled The Steve Allen Show; this premiered in 1953 on the local station affiliate in New York City. Beginning in September 1954, it was renamed Tonight! and began its historic run on the full NBC network. Notes for hosting history The first Tonight announcer was Gene Rayburn. Allen's version of the show originated talk show staples such as an opening monologue, celebrity interviews, audience participation, comedy bits in which cameras were taken outside the studio, as well as music including guest performers and a house band under Lyle "Skitch" Henderson; when the show became a success, Allen got a primetime Sunday comedy/variety show in June 1956, leading him to share Tonight hosting duties with Ernie Kovacs during the 1956–57 season. To give Allen time to work on his Sunday evening show, Kovacs hosted Tonight on Monday and Tuesday nights with his own announcer and bandleader.

During the Steve Allen years, regular audience member Lillian Miller became such an integral part that she was forced to join American Federation of Television and Radio Artists, the television/radio performers union. She would continue to perform the same service for most of the major talk shows for decades, including those hosted b

Mexicans are the people of Mexico, a country in North America. The Mexica founded Tenochtitlan in 1325 as an altepetl located on an island in Lake Texcoco, in the Valley of Mexico, it became the capital of the expanding Aztec Empire in the 15th century, until captured by the Spanish in 1521. At its peak, it was the largest city in the Pre-Columbian Americas, it subsequently became a cabecera of the Viceroyalty of New Spain. Today the ruins of Tenochtitlan are located in the central part of Mexico City; the modern nation of Mexico achieved independence from the Spanish Empire. This led to what has been termed "a peculiar form of multi-ethnic nationalism"; the most spoken language by Mexicans is Mexican Spanish, but some may speak languages from 68 different indigenous linguistic groups and other languages brought to Mexico by recent immigration or learned by Mexican immigrants residing in other nations. In 2015, 21.5% of Mexico's population self-identified as being Indigenous or Indigenous. There are about 12 million Mexican nationals residing outside Mexico, with about 11.7 million living in the United States.

The larger Mexican diaspora can include individuals that trace ancestry to Mexico and self-identify as Mexican. The Mexican people have varied origins and an identity that has evolved with the succession of conquests among Amerindian groups and by Europeans; the area, now modern-day Mexico has cradled many predecessor civilizations, going back as far as the Olmec which influenced the latter civilizations of Teotihuacan and the much debated Toltec people who flourished around the 10th and 12th centuries A. D. and ending with the last great indigenous civilization before the Aztecs. The Nahuatl language was a common tongue in the region of modern Central Mexico during the Aztec Empire, but after the arrival of Europeans the common language of the region became Spanish. After the conquest of the Aztec empire, the Spanish re-administered the land and expanded their own empire beyond the former boundaries of the Aztec, adding more territory to the Mexican sphere of influence which remained under the Spanish Crown for 300 years.

Cultural diffusion and intermixing among the Amerindian populations with the European created the modern Mexican identity, a mixture of regional indigenous and European cultures that evolved into a national culture during the Spanish period. This new identity was defined as "Mexican" shortly after the Mexican War of Independence and was more invigorated and developed after the Mexican Revolution when the Constitution of 1917 established Mexico as an indivisible pluricultural nation founded on its indigenous roots. Mexicano is derived from the word Mexico itself. In the principal model to create demonyms in Spanish, the suffix -ano is added to the name of the place of origin, it has been suggested that the name of the country is derived from Mextli or Mēxihtli, a secret name for the god of war and patron of the Mexicas, Huitzilopochtli, in which case Mēxihco means "Place where Huitzilopochtli lives". Another hypothesis suggests; this meaning might refer to Tenochtitlan's position in the middle of Lake Texcoco.

The system of interconnected lakes, of which Texcoco formed the center, had the form of a rabbit, which the Mesoamericans pareidolically associated with the Moon. Still another hypothesis suggests that it is derived from the goddess of maguey; the term Mexicano as a word to describe the different peoples of the region of Mexico as a single group emerged in the 16th century. In that time the term did not apply to a nationality nor to the geographical limits of the modern Mexican Republic; the term was used for the first time in the first document printed in Barcelona in 1566 which documented the expedition which launched from the port in Acapulco to find the best route which would favor a return journey from the Spanish East Indies to New Spain. The document stated: "el venturoso descubrimiento que los Mexicanos han hecho"; that discovery led to the Manila galleon trade route and those "Mexicans" referred to Criollos and Amerindians alluding to a plurality of persons who participated for a common end: the conquest of the Philippines in 1565.

A large majority of Mexicans have been classified as "Mestizos", meaning in modern Mexican usage that they identify neither with any indigenous culture nor with a Spanish cultural heritage, but rather identify as having cultural traits incorporating elements from indigenous and Spanish traditions. By the deliberate efforts of post-revolutionary governments the "Mestizo identity" was constructed as the base of the modern Mexican national identity, through a process of cultural synthesis referred to as mestizaje. Mexican politicians and reformers such as José Vasconcelos and Manuel Gamio were instrumental in building a Mexican national identity on the concept of mestizaje. Since the Mestizo identity promoted by the government is more of a cultural identity than a biological one it has achieved a strong influence in the country, with a good number of biologically white people identifying with it, leading to being considered Mestizos in Mexico's demographic investigations and censuses due the ethnic criteria having its base on cultural traits rather than biological ones.
