Lost and Alias are really the only shows I make it a point to watch. Since Alias is canceled, I wouldn't call it hugely popular.
I Tivo:
The OC
Las Vegas
How I Met Your Mother
Desperate Housewives
What About Brian
Love Monkey (canceled but VH1 is airing the already produced episodes, I think there is 1 left)
American Idol
So NoTORIous
Of the show's I Tivo I run about a week behind. Currently I'm 3 weeks behind on Desperate Housewives and 2 week's behind on both Las Vegas and The OC. I tend to FF through American Idol, just to see who was voted off. I haven't watched since Queen week but I've jumped to the end of the results show.
