Gregg Whiteside, who for 17 years hosted weekday morning programming and the Philadelphia Orchestra concert broadcasts at WRTI, abruptly disappeared from the air last month, with only a brief farewell note about his retirement (as it was termed) several days later on the station’s website. The staff had been alerted with a one-sentence memo saying that Whiteside no longer works there “effective immediately,” and station execs have said absolutely nothing about the matter since. – Broad Street Review (Philadelphia)
