TA had already acquired a 30 percent stake in United Broadcasting. In part because of a lawsuit filed against the estate by competing cable system Continental Cablevision claiming a right of first refusal agreement to purchase the system was not honored, the sale agreement between TA and United expired in January 1990 and the deal did not close. At the same time, WJMO began facing increasing ratings pressure from crosstown WZAK, which in 1981 successfully switched formats from block ethnic programming to urban contemporary. On January 22, 1990, WRQC changed their call letters back to WJMO-FM (92.3) and entered into a hybrid "Churban" Urban/CHR format with WJMO under the "Jammin' 92" brand, with both stations simulcasting during morning and afternoon drive time. At all other times, WJMO moved to a gold-based R&B oldies format with the "Solid Gold Soul" brand, having dropped most current music from their playlist, while WJMO-FM continued with the hybrid CHR programming. The drive time simulcasts ended by that October, with each station adopting their respective format full-time. Contested sale, then NewCo United Broadcasting sold WJMO and WJMO-FM in October 1992 to Zebra Communications for a reported $4.445 million. Zebra was a partnership between WZAK owner Zapis Communications, WZAK program director Lynn Tolliver, and WZAK music director Bobby "Otis" Rush; both Tolliver and Rush were long-time radio personalities in the market, and both had previously worked at WJMO. Although Tolliver and Rush were both African-Americans, they only had 23 percent of the company's equity, and 57 percent of the company's voting stock. Zapis held the remainder of equity and voting stock and was considered the key party in the new ownership, a joint sales agreement was also filed between the stations and WZAK allowing shared management and operations. Both the Cleveland chapters for the NAACP and the SCLC, along with five different community groups, contested the sale. The SCLC filed a petition against Zapis Communications in December 1992, alleging that Zapis committed fraud by using WZAK employees to get the stations at a cheaper price while Zapis effectively would be controlling all operations. The sale was approved by the FCC on May 20, 1993, and WJMO and WJMO-FM became the first radio stations in the Cleveland radio market with significant African-American ownership. Because Zebra was interpreted as a minority-owned group due to the presence of Tolliver and Rush, the FCC also approved a $1.7 million tax
