WLW is a radio station located in Cincinnati, Ohio, run by Clear Channel Communications and is located at 700 AM. The station runs under the talk format and is the flagship station for The Truckin' Bozo, a popular nationwide, overnight program especially for truckers. Its studios are in the Kenwood section of Sycamore Township and its transmitter is located in Mason.

WLW currently broadcasts using 50,000 watts (50-kW) of power, but that wasn't always the case. For about six years WLW experimented with broadcasting at 500,000 watts, the first station in the world to do so, during the overnight hours under callsign W8XO. It stopped in 1939 because of complaints from around the United States and Canada that WLW was overpowering other stations as far away as Toronto. WLW powered up again a few times during WWII in order to send special broadcasts to American troops in Europe, and has not broadcasted at 500,000 since then.

The station was started by radio manufacturer Powel Crosley Jr. and operated by the Crosley Broadcasting Corporation until the 1960s.

The station's first 50-kW transmitter, made by Western Electric, is still functional and sees very occasional service. On December 31, 1999, it was powered up, and served to bring WLW into the year on January 1, 2000.
