The story
In 1923, Ross Sterling Jr. took a course on broadcasting at the YMCA in Houston. His father, Ross Sterling Sr., met the instructor, Alfred P. Daniel (of now-discontinued radio station WCAK), and discussed starting a new radio station affiliated with the Houston Post. William P. Hobby, the president and publisher of the Post, asked Sterling to launch the radio station. Before a 500 watt transmitter ordered from the Westinghouse Electric Manufacturing Co. arrived in Houston, Sterling Jr. died. Sterling Sr., mourning the loss of his son, put the still crated transmitter in storage. Over one year later, Daniel approached Sterling Sr. and asked about proceeding with the establishment of the radio station. Sterling Sr. agreed with the idea and moved forward with establishing the station. KPRC's first broadcast occurred on Saturday May 9, 1925, with Daniel as the station's first announcer and program director. The federal license granting permission for radio broadcasts on 920 kHz was issued on May 13. (In 1941, KPRC moved to its current frequency of 950 kHz under terms of the North American Regional Broadcasting Agreement.)
