You would think that in Chicago, it would be hard for WBBM’s ratings to go any lower.

But, Robert Feder writes that the CBS O&O’s ratings have taken a dip do to the fact that the station and the rest of the CBS O&O’s are in a retrans pissing match with DirecTV.

Feder writes, the ongoing impasse between CBS and AT&T is wreaking havoc on WBBM’s already low ratings. The blackout of CBS 2 on DirecTV, DirecTV Now and U-verse cable systems appears to have cost the CBS-owned station more than a quarter of its viewership.

Nielsen household ratings dropped an average of 28 percent around the clock last week, with some time periods (including CBS 2’s 10 p.m. newscast) down as much as 33 percent.

Ouch!
