A busy news day of combative Congressional Obamacare hearings and Presidential speeches did CNN no favors in primetime last night. The Jeff Zucker-run cable network hit its lowest primetime time result among adults 25-54 in over a year Wednesday despite all the cable newers being up double digits over the day before during Health and Human Services Sec. Kathleen Sebelius’ morning testimony. Between 8 PM and 11 PM last night, CNN had a mere 67,000 viewers among the key news demo. That’s the worst its done in the demo since August 10 last year. With the Olympics were on NBC last August, CNN drew just 62,000 among the 25-54s that Friday. Not only was CNN behind rivals Fox News Channel (396,000) and MSNBC (127,000) but also it did worse than sister station HLN (93,000) and CNBC (79,000). The most watched show on CNN last night was Piers Morgan Live at 9 PM which got a soft 83,000 in the demo and 340,000 viewers overall. Overall CNN had 285,000 viewers in primetime last night compared to MSNBC’s 683,000 and FNC’s 2.312 million.
