WGBO-DT (channel 66) is a television station licensed to Joliet, Illinois, United States, serving as the Chicago-area outlet for the Spanish-language network Univision.

The two stations share studios at 541 North Fairbanks Court in the Streeterville neighborhood; WGBO-DT's transmitter is located atop the John Hancock Center.

Combined Broadcasting, the consortium of creditors formed in the wake of Grant's bankruptcy, sold the station to Univision in 1994, giving the network its first full-time outlet in Chicago in six years.

[5] Murchison provided financing for the station, guaranteeing loans of up to $7 million for its construction in exchange for most of the revenue to be garnered from STV programming.

[8] Several months later, Buford sold a majority 80 percent stake in its STV interests, grouped under the Home Entertainment Network banner, to United Cable of Denver for $20 million.

[11] It tied up almost all of channel 66's broadcast hours, with WFBN's lone free offerings being a daily exercise show and a public affairs program aired twice a week.

Operational responsibilities were transferred to UPI, the wire service that Focus principals Douglas Ruhe and William Geissler had purchased in 1982.

With many program distributors having gone unpaid, some since September 1984, Focus and Grant warned that any failure to approve the deal would likely lead to the station leaving the air or even involuntary bankruptcy.

Metrowest Corporation, then-owners of competing WPWR-TV (channel 60), filed a petition to deny the sale, claiming that even before it acquired the WFBN license, Grant had attempted to "stifle competition in the Chicago television market with multimarket program purchases, exclusive arrangements and similar deals".

[21] After the FCC approved Grant's purchase of WFBN in November 1985,[22] the station changed its call letters to WGBO-TV on January 4, 1986, adopting "Super 66" as its on-air branding.

[23] Although not dramatically different overall, in January 1986, WGBO added a few more off-network sitcoms, a limited number of children's programs, and several western series to its schedule, as well as daily simulcasts of CNN Headline News.

[31] For the next five years, WGBO subsisted on reruns, infomercials, and a variety of local programs of secondary interest: local religious programs (including the Catholic Mass) dropped by WGN-TV,[32] a country music video show from radio station WUSN,[33] the Hoosier Millionaire lottery game show in Indiana,[34] and University of Illinois and syndicated Big Ten Conference college basketball.

Even though Tribune Broadcasting would hold a partial ownership interest in The WB and tapped its independent stations in other markets to serve as the network's charter affiliates, WGN-TV was not initially expected to affiliate because of its national superstation feed and extensive sports programming, and network president Jamie Kellner told Electronic Media that The WB was more likely to be seen in Chicago on WGBO.

While the deal included most of WGBO's non-license assets such as its studio facilities, transmission equipment and transmitter, it excluded its English-language programming inventory.

On January 1, 1995, WGBO switched to Spanish-language programming, giving Univision a full-time presence in the market for the first time since 1989, when the network disaffiliated from WSNS-TV to return to WCIU.

[53] Most of WGBO's syndicated inventory, as well as Hoosier Millionaire, was picked up by a new independent station in Hammond, Indiana, WJYS,[54] while the Catholic Mass moved to WEHS-TV.
