The industriousness of reader MikeS has yet to reach its bounds. Courtesy of his work, we now have an adults 25-54 demo (which is the group targeted by cable news advertisers) long term chart as well as an average viewership chart.
Long Term Trend of O'Reilly vs. Olbermann vs. Campbell Brown TV Ratings:
The trend lines above are 30 day moving averages.
For complete information on all cable news ratings check our daily cable news ratings posts.
I stopped producing these charts in the spring of 2009 because of lack of interest (some on my part, some on the readers), but energetic reader MikeS wanted to produce them, and I think they look better than mine did! Anybody else wanting to produce trend charts of any of our other data, drop me an email.
