"Importance of Parameters" studies done by The Research Group in Raleigh in the 80s showed traffic reports in the morning as very important - almost as high as weather reports. Only WPTF and WRAL had traffic reports in those days. We brought TPB to the market to dilute their impact. Suddenly everyone had them.
In Winston-Salem, the state paid WSJS and WTQR to air traffic reports for the downtown area while they build the downtown expressway (later became I-40, now Business 40). After the project was over, listeners felt the reports were valuable and the stations expanded them to cover the region. SJS/TQR flew two airplanes (JR in one and JJ in the other).
TPB came along, took over the operation of the planes and added most of the stations in the market (1989).
This doesn't sound right. WTQR was WSJS-FM when Business 40 was being built.
And I got interested in the subject some years ago and went to the top floor of the library where they had a folder full of articles on the construction of Business 40. At the time, it was supposed to be nothing more than what it is now. Then someone came up with the bright idea of making that the interstate instead of building a bypass.
