Over a decade ago, a DJ I know was at a radio station meeting. A consultant announced that the format to which the station was switching had never been done in St. Louis. Later in the meeting, the DJ told him, "Actually, (this format) has been done here before." "No," he replied. "It hasn't been tried here." "Yes, it has," she replied. "I did afternoon drive at (the previous station with that format.)" "Oh," he replied sheepishly. "I told (the new radio station's powers that be) it hadn't been done in this market."
It's easy to proclaim something is historical when you don't know its history.
