From the late 1960s until 1985, WCIU carried religious programs during the early morning hours. The station ran "The Stock Market Observer"—a business news block similar in format to the present-day cable channel CNBC—from about 8:00 a.m. to 3:30 p.m. each weekday; the service broadcast from the trading floor of the Chicago Board of Trade, with WCIU originally maintaining studio facilities at the top floor of the Chicago Board of Trade Building on West Jackson Boulevard. After 5:00 p.m. each weekday, the station ran Spanish language entertainment programming—including controversial bullfighting matches—from the Spanish International Network (the forerunner to Univision). During the weekend, WCIU ran a blend of religious programs, Spanish language programs, paid programming and various other ethnically-oriented shows.
