Stern Losing Throne?: Howard Stern, the self-proclaimed "king of all media," may soon be officially dethroned in Los Angeles. In the latest Arbitrends, which averages three months' worth of ratings compiled by the Arbitron ratings service, Stern dropped to fourth place, behind top-ranking Spanish station KLAX-FM, Rick Dees on KIIS-FM and AM and Mark and Brian on KLOS-FM. Dees emerged as the top-ranking English-speaking morning-drive jock, drawing an average of 6% of the audience to the KLOS duo's 5.8% and Stern's 5.5%. The Arbitrends are sometimes an indication of what the next official quarterly survey (due in April) will show.
