Input: Question: How long had Infinity Broadcasting been in existence by the year that it acquired ARS as part of a group deal? Passage:Taft Broadcasting would be reorganized as Great American Broadcasting in 1987. However, the company would declare bankruptcy in 1993, and was reorganized as Citicasters, Inc. (their sister AM station would be sold to another locally-based company, Jacor). In 1996, Citicasters itself merged with Jacor; as part of the merger, WKRQ was sold to Boston-based American Radio Systems (ARS) on March 7, 1997 (this separated WKRQ from their long-time TV sister station). However, in September 1997, Infinity Broadcasting (which was renamed CBS Radio in December 2005) would acquire ARS as part of a group deal; the merger was completed the following June. CBS owned WKRQ until November 2006, when it was sold to Entercom. Entercom, in turn, announced in January 2007 that it would be swapping its entire Cincinnati cluster, including WKRQ, to Bonneville International together with three radio stations in Seattle, Washington, for all three of Bonneville's FM radio stations in San Francisco, California, and $1 million cash. In May 2007, the station launched an online stream from its website at www.wkrq.com. Also that month, Bonneville officially took over the operations of Entercom's former Cincinnati radio cluster through a local marketing agreement. Entercom officially closed on its acquisition of the stations on November 30. The sale of the Cincinnati cluster to Bonneville was conditionally approved in November 2007, with the remainder of the deal finally approved in March 2008. The official transfer of the Cincinnati stations to Bonneville took place on March 14.
