by the mid-1980s. The teletype sound effect was eventually dropped by the late 2010s. WINS used memorable slogans such as "All news, all the time"; "The newswatch never stops"; "Listen two, three, four times a day"; and "You give us 22 minutes, we'll give you the world"; the latter tagline was a reference to WINS's format clock, which returns to the top stories every twenty minutes. WINS's switch to all-news was initially viewed as a risky programming choice. Tijuana, Mexico-based border blaster XETRA had programmed an English-language all-news format for the Los Angeles radio market, as had Chicago station WNUS and, previously WAVA AM and FM in the Washington, D.C. area. Locally, WABC-FM aired a news format for several weeks during the 1962–63 New York City newspaper strike. None of the other attempts were successful, and as a result many in the radio industry predicted a quick demise for WINS, however, Westinghouse Broadcasting supported the format and WINS eventually prospered with it. Westinghouse made similar format changes at two other stations: KYW in Philadelphia, in September 1965; and KFWB in Los Angeles, in March 1968. Together, WINS, KFWB and KYW served as prototype all-news stations, and all three succeeded in attracting both listeners and advertising revenue over the years. In 1995, Westinghouse Electric purchased CBS, a move which put WINS under common ownership with WCBS. Despite initial speculation after the merger that either station would drop the all-news format, both stations remained in place and are among the most successful radio operations in the U.S. in terms of advertising sales. The two stations have their own areas of dominance; WINS's ratings numbers are better within New York City, while WCBS's listener strength is greater in the suburbs, owing primarily to its much stronger signal. From a programming standpoint, they have different styles (hard news, vs. lighter and conversational) to appeal to different listeners. Since the Westinghouse-CBS merger, both stations have continued to perform well in both ratings and advertising revenue. WINS's signal was also improved in 1995 after the company bought KSYG in Little Rock, Arkansas, which had also broadcast on the same frequency, and took it off the air. This relieved WINS of the need to "null" its signal in the direction of Little Rock. WINS' towers in Lyndhurst, New Jersey, which were shorter than optimum for its frequency, were replaced with four taller ones. While the signal is
