75 years ago today, the May 17, 1943, issue of Broadcasting carried this ad by Westinghouse regarding its shortwave outlet, WBOS Boston.

The illustration shows some listeners, presumably clandestine ones, tuned into the station, with the lofty caption that the truth will set them free.

The ad explains that untold millions in occupied Europe might be listening to the short waves bringing them truth, works of hope and promise. Westinghouse had 22 years of shortwave experience, and brought the same crystal-clear and trustworthy programs to domestic audiences on it broadcast stations, WOWO, WGL, WBZ, WBZA, KYW, and KDKA.

More information about WBOS can be found at our earlier post.
