Question: Is Craig T. Nelson being cast on CSI: NY just another big star guest turn or could it be something more important? We don't know the answer yet, but I suspect that booking the Emmy-award winning TV star for three episodes could be a lot more significant than just pumping up the ratings during February sweeps with a meaty story arc.

What we do know is that the popular actor will be on CSI: NY as an antagonist to Gary Sinise's character. Nelson will play Robert Parker, a high profile, powerful publisher who has an ax to grind with Mac Taylor.

To say they're going to butt heads is an educated guess, but I think that's the direction they're going. You can see Parker using his media outlets to attack Mac and his department, you know, those great New York tabloid headlines.

So, do you still watch the network news at night?

I watch it, but not every night. I usually channel surf and watch one of the news broadcasts or maybe a repeat of Will and Grace or Seinfeld if there's a good episode on. But there are still a lot of people who watch the broadcasts (mostly an older demographic, judging from the ads they run), and it looks like ABC's World News is hot right now. The show will win the February sweeps ratings for the first time since November 2001 (in both total viewers and the 25 to 54 demo), and while Gibson's show has gained 60,000 viewers, The NBC Nightly News has lost an average of 570,000.

Oh, and rumor has it that Katie Couric does a newscast over on CBS too.
