The series reflects the rich diversity and breadth of human experience that shaped this great American city.

Sneak Previews was an American film review show, running for over two decades on Public Broadcasting Service. It was created by WTTW, a PBS affiliate in Chicago, Illinois. It premiered on September 4, 1975 as a monthly local-only show called Opening Soon at a Theater Near You, and was renamed in 1977 when it became a biweekly show airing nationally on PBS. By 1979, it was a weekly series airing on over 180 stations, and was the highest rated weekly entertainment series in the history of public broadcasting. It was finally cancelled in 1996.

Chicago Tonight is an evening television news program broadcast weeknights on WTTW in Chicago. Chicago Tonight reports primarily on local news and presents features showcasing local artists and events. The show began April 24, 1984 and was hosted by popular Chicago broadcast journalist John Callaway for fifteen years. He continued to contribute to the show until he died in 2009.

Monday through Thursday night the program is hosted primarily by Phil Ponce. On Friday, Joel Weisman hosts Chicago Tonight: The Week in Review a panel discussion with four journalists on the top stories of the week.

Check, Please! is a popular restaurant review program that first aired on Chicago's PBS member station WTTW in 2001. The show's popularity inspired spin-offs in several other markets. A San Francisco version of the show, Check, Please! Bay Area, began its first season in 2005, airing on KQED. A Miami version for WPBT, Check, Please! South Florida, debuted in January 2008. Check, Please! Kansas City then began airing on KCPT in 2009, and Check, Please! Arizona on Phoenix's KAET made its debut in 2010. A Seattle version, Check, Please! Northwest, began airing on KCTS in 2012.

The format of the show is simple: three people sit down with a host to discuss three local eating establishments, one favorite chosen by each guest. Before the program is taped, each person chooses a favorite restaurant, and everyone in the group is required to visit each person's selection. Afterwards, everyone describes their eating experiences. Although many participants select trendy, upscale restaurants, just about any eating establishment is fair game including hot dog stands and "neighborhood joints".

Wild Chicago was a television series that aired on Chicago's WTTW from 1989 to 2003. The show took viewers on a trip through Chicago's "urban jungle", highlighting hundreds of offbeat and unusual people, places, and events in the metropolitan area. Subjects included the Chicago Herpetological Society; singing taxicab drivers; flotation tanks; an Ancient Astronaut society; the Inkin' Lincoln Tattoo and Piercing Jamboree; an interstate pierogi festival; a squirrel lovers' club; the Playboy Advisor; a cookie jar museum; and the Polka Music Hall of Fame.

Wild Chicago was created by Ben Hollis and John Davies. The series won numerous local Emmy Awards over the course of its run, as did several of the show's hosts. Emmy Award winners for their individual work include Hollis, the show's original host, and his replacements upon taking an extended hiatus in 1992, Laura Meagher and Will Clinger. When, after two years, Meagher left the show to work for Fox Television, then to launch and be featured on Barry Diller's independent channel, WAMI in Miami, Wild Chicago changed to a multiple correspondent/contributor format, a trend in such television magazine shows of the mid-1990s. Contributors included local actors Mindy Bell, Cassy Harlo, Tava Smiley, Sarah Vetter, Denise La Grassa, Choky Lim, Aaron Shure, and Dick O'Day. The new slate of correspondents continued to win individual Emmys as did the show itself.
