KYW (1060 AM) is a commercial radio station licensed to serve Philadelphia, Pennsylvania. It is one of the oldest radio stations in America, originating in Chicago and moving to Philadelphia in 1934. KYW's unusual history includes its call sign of only three letters, beginning with a K, rare for a station in the east. It broadcasts an all-news radio format and, due to its simulcast on WPHI-FM, is branded as "KYW Newsradio." KYW serves as the flagship station of Audacy, Inc. KYW's studios are co-located within Audacy's corporate headquarters in Center City, Philadelphia, and its transmitter and two-tower directional antenna array are located in Lafayette Hill.
