This building gets mentioned in the media even more than the Sears Tower. That’s because its address is also the name of a television show on WLS-TV/DT (channels 7 and 52). But the structure’s entertainment heritage pre-dates electronic media. This building was originally erected to house the State-Lake Theater. Its façade is white terra cotta, and contains a number of minor decorative flourishes that when combined give the impression of delicate decoration. Just a few years later the same architects, Rapp and Rapp, would build the far more impressive Chicago Theater across the street.

By the time World War Two started, the heyday of the battling Chicago theaters was waning. But 190 North State Street would become the center of a new form of local entertainment: television. Above the theater section of this building are ten stories of offices. It was from here in 1940 that television station W9XBK went on the air. Those call letters mean little to most people today. The television station they represent eventually became WBKB, and later WBBM-TV, then back to WBKB, and eventually WLS-TV when theater owners Balaban and Katz sold the operation to the ABC network.

There is a Chicago urban legend (repeated in some architecture books) which states that WLS-TV was the first television station in Chicago, and the third-oldest in the nation. This is simply not true. The first television station in Chicago was W9XAA, which went on the air 12 years before W9XBK/WBKB/WBBM-TV/WLS-TV. It was the television arm of what was then the Chicago Federation of Labor’s WCFL radio. Several other television stations joined it and were broadcasting a lineup and information and entertainment shows years before the early form of WLS-TV (then known as WENR-TV) ever went on the air.

But the broadcasting heritage of 190 North State Street cannot be denied. This building eventually became home to WLS radio as well. It's call letters symbolizing "World's Largest Store" because its owner was the legendary department store chain (and former catalog operator) Sears Roebuck and Company. Being in the heart of the theater district helped lure performers to the studio from neighboring theaters, and helped solidify this building’s position in the Chicago broadcasting history books.

In 2006, WLS Television's building once again gained attention by transforming itself into a tourist attraction. In April of that year the State Street Studio went into operation. This facility allows the general public to peer in and see a working television studio. WLS-TV/DT is actually the second station in Chicago to allow such an opportunity. A few blocks away, WMAQ-TV/DT (channels 5 and 29) gives the viewing public the same chance at space it rents in the Equitable building on Michigan Avenue. Also going street-side is WBBM-TV/DT (channels 2 and 3), which plans to open a street-front studio at 108 North State -- virtually across the street from the WLS operation.
