remnants of Taft International Pictures and Taft Entertainment Television), except for the Hanna-Barbera and Ruby-Spears libraries, which remained owned by Great American for the time being. However, Worldvision continued to hold syndication rights until the two animation studios found new owners. In 1991, Hanna-Barbera, along with much of the original Ruby-Spears library, was acquired by Turner Broadcasting System, which became part of Time Warner in 1996. As part of this deal, syndication rights to the libraries were passed to Turner Program Services (via Turner Entertainment Co.) prior to Time Warner's purchase of Turner. Eventually, TPS was folded into Warner Bros. Television Distribution. The Ruby-Spears studio was spun off and bought back by Joe Ruby and Ken Spears, and operated as an independent operation from then forward. In 1992, KECO Entertainment, Great American's theme park division, was sold to Paramount Communications (the parent of Paramount Pictures; the parent company was formerly known as Gulf+Western) and became Paramount Parks, later to be acquired by Viacom. (These parks were sold to Cedar Fair Entertainment Co. by CBS in 2006.) Great American also reacquired WGHP from Dudley Taft. In 1993, Great American filed for Chapter 11 bankruptcy and renamed to Citicasters Communications. It also sold WKRC radio to Jacor and shut down Electra, a teletext service operated as a joint venture between Taft, Zenith, and Turner Broadcasting's WTBS (now WPCH-TV) in Atlanta. In 1994, Citicasters sold most of its TV stations, including WDAF-TV and KSAZ-TV to New World Communications, and WBRC and WGHP to the News Corporation's Fox Television Stations unit, which would later acquire the New World chain. Around the same time, when two of the markets switched to ABC via Scripps, Citicasters agreed to a two-station deal with CBS to affiliate with WTSP and WKRC. In 1996, Citicasters, by then the owner of two television stations, five AM radio stations and 14 FM radio stations, merged with Jacor, which became a subsidiary of Citicasters. Three months after the merger was completed, Jacor exchanged WTSP to Gannett in return for Gannett's radio stations in Los Angeles, San Diego and Tampa. In 1997, as a condition of the merger, Jacor sold WKRQ and the original WDAF-FM (by then KYYS, now KCKC) to American Radio Systems, which would become acquired by Infinity Broadcasting (later renamed CBS Radio) in 1998. Also in 1997, Jacor sold WDAF (AM) (now KCSP) to Entercom. In 1997, the Worldvision properties
