Not everyone has Showtime or the ability to sign up for it just for Jeremiah ... no matter how good anyone says it is. Also, I think that many who read the moderated newsgroup are -already- tuning in if they are able. What I could see happening is the fans telling their friends to tune in and any casual viewers to tune in for the finale. Not terribly promising really."
I suspect most of the falloff in ratings is due summer vacations and other activities besides watching TV. I'm basing this on traffic for my web site and on the University of Kansas-sponsored discussion list I co-own. Since the first of July traffic on both has fallen off to about 30% of normal monthly traffic. Looking back at past traffic records, this has been the norm for early July, with traffic picking up in late July - early August. True, both the discussion list and my web site are academic but in other summer months traffic is only 10-15% below school year normal. This pattern leads to suspect that TV viewing falls off during this same time frame, albeit not to the extent for an academic web site/discussion list.
If this assumption is in the ball park, it follows that Showtime, other networks and advertisers know and take this factor into consideration when looking at viewer numbers for this time frame.
In other words, the drop in the number of viewers for the past few eps may not be as bad it as it looks to us outside the decision process.
