Chicago is the largest city by population in the state of Illinois and the American Midwest of the United States. Adjacent to Lake Michigan, the Chicago metropolitan area has a population of over 9.7 million people in three U.S. states, Illinois, Wisconsin and Indiana, and was the third largest metropolitan area in 2000. One of the largest cities in North America, Chicago is among the world's twenty-five largest urban areas by population, and rated an alpha world city by the World Cities Study Group at Loughborough University. It is the third-most populous city in the United States after New York City and Los Angeles, with a population of nearly 3 million people. Chicago incorporated as a city in 1837 after being founded in 1833 near a portage between the Great Lakes and the Mississippi River watershed. The city soon became a major transportation hub in North America and the transportation, financial and industrial center of the Midwest. Today the city's attractions bring 44.2 million visitors annually. Chicago became notorious worldwide for its violent gangsters in the 1920s, most notably Al Capone, and for the political corruption in one of the longest lasting political machines in the nation. Chicago was once the capital of the railroad industry and until the 1960s the world's largest meatpacking facilities were at the Union Stock Yards. O'Hare International is one of the world's busiest airports and the second busiest in the nation. The city has long been a stronghold of the Democratic Party and has been home to numerous influential politicians including the current Democratic presidential nominee, Barack Obama. Chicago is called the Windy City and the City of Broad Shoulders.

Infomercial Format

Infomercials are long-format television commercials, typically five minutes or longer. The distribution of Infomercials is via paid programming. This phenomenon started in the United States where infomercials typically shown overnight --outside of peak hours. Some television stations chose to air infomercials as an alternative to the former practice of sign-off. By 2009, most US infomercial spending is during early morning, daytime, and evening hours. Stations in most countries around the world have instituted similar media structures. Over $150 billion of consumer products in the U.S. sold through infomercials. Infomercial is sometimes misapplied and used to refer to direct response television advertisements of 60 to 120 seconds in length. However, the term describes program length advertisements. In the US, they are typically 28 minutes and 30 seconds in length. In the US, DRTV advertisements of 30 seconds to 2 minutes in length are typically called "short form" or "DRTV spots" and are not included in the advertising industry's use of the term "infomercial". Note that in the US market, a small amount of media can be purchased for 5 minutes length advertisements, although this time is quite limited. Outside of the US market, lengths depend on the lengths allowed by television stations and government regulators. Infomercial was originally applied only to television advertising; it is now sometimes used to refer to any presentation with a significant amount of information in an actual, or perceived, attempt to persuade to a point of view. When used this way, the term may be meant to carry an implication that the party making the communication is exaggerating truths or hiding important facts. Often, it is unclear whether the actual presentation fits this definition because the term is used in an attempt to dis-credit the presentation. In this way, political speeches may be derogatorily referred to as "infomercials" for a specific point of view.
