Right now, the only TV shows currently airing on TV that I'm watching are the Ben 10 series (Ultimate Alien, of course, just ended, with Omniverse starting up in the fall), Star Wars: The Clone Wars, and Ghost Adventures. I'm also watching Naruto: Shippuden when they get the episodes dubbed in English (since I admittedly far prefer the English dubbed version to having to watch it in Japanese with English subtitles).
Sometimes I'll watch something on TLC, the History Channel, etc. if it's a particular program on something that strikes my fancy. (Sometimes I'll watch the local news to catch things like the weather report.)
I'm also working my way through the old Robotech series (through Netflix), and need to get back to watching "Heroes" (which I can't believe they went and cancelled!).
