A cable news channel is earning some of its lowest ratings in decades. The New York Post reports that in the key news demo of viewers 25-54, CNBC is attracting an average of just 37,000 viewers this month in total day.

That’s down 35% from a year ago, the story reports, citing Nielsen data. It’s also the worst ratings draw for CNBC in the 25-54 demo since April 1993. A CNBC representative said Nielsen’s current rating system undercounts viewers.

CNBC’s peak in the key demo was in January 2002, when 162,000 viewers in that age group tuned in, the story adds.

August has been a challenging month for cable news channels in general, with Fox News falling 24% in the key demo in total day, and MSNBC down 32%, the piece notes. CNN bucked the trend, climbing 13%, while its sister channel HLN was off 9%.
