Detroit Ratings Revision Drops WWJ Share
October 1, 2008 at 5:07 AM (PT)
A mistake in measurement has resulted in the reissuing of the DETROIT ARBITRENDS and a downward revision for CBS News WWJ-A/DETROIT, which drops from a 6.4 share of persons 12+ and a #1 ranking to a tie for fourth place and a 5.1 share.
The problem came about because ARBITRON initially ascribed the station's figures to a daytime-only schedule, while the station actually operates around the clock. CLEAR CHANNEL Urban AC WMXD (MIX 92.3) takes over the 12+ top ranking with a 5.4 share.
