Campbell Brown's 8pmET CNN program had just 69,000 viewers in the A25-54 demo Friday night - the program's lowest ever. In fact, it was the lowest demo viewership for CNN at 8pmET since Christmas Day 2007.

The previous program low was 115,000, which occurred May 20 when Roland Martin was filling in. Brown's previous low was last Wednesday, with 125,000 viewers.

Brown took over anchoring the 8pm hour in March 2008 when the show was called "Election Center." The show morphed into "Campbell Brown: No Bias, No Bull" in October, a response to her 8pm competitors on Fox News and MSNBC. When she returned from maternity leave earlier this month the show was renamed "Campbell Brown."

Friday night was also the lowest A25-54 demo total of the year for Anderson Cooper 360, with 98,000 viewers, and the lowest Total Viewer average for Brown (591,000) in 2009. (Cooper's 10pm hour and repeated at 11pm was a taped special called "The Lone Wolf.")

The low viewership, on a summer Friday, came on the day of big international news as the results of the Iranian presidential election were coming in.

A CNN spokesperson tells TVNewser: "It's one summer Friday. CNN offers viewers the only non partisan news programming in prime time and will continue to report the hard news of the day."
