On Jan. 20, NBC is revamping its heralded "Must-See TV" Thursday nights with a new three-hour comedy block. Joining 'Community,' 'The Office,' '30 Rock' and 'Outsourced' will be the return of 'Parks and Recreation' and the brand-new show 'Perfect Couples.'

So far the new sitcom appears to be NBC's answer to their rival ABC's runaway success, 'Modern Family.' Both shows feature three different families of normal, yet surprisingly quirky, upper-middle-class characters; 'Perfect Couples' is simply the younger version. Whether the show is in reaction to the other or not, the three separate, interconnecting story lines do allow for a lot of quick jokes.

While 'Modern Family' introduced us to a number of new actors, the cast of six should be familiar to TV fans. David Walton, Mary Elizabeth Ellis, Christine Woods, Kyle Bornheimer, Hayes MacArthur and Olivia Munn all have had their fair share of small screen time.

On the new sitcom '100 Questions' (Thu., 8:30PM ET on NBC), a group of friends try to find love while hanging out in the big city. Hmm. That description sounds oddly familiar. It's almost as though we've seen this type of show before or something.

[Spoiler alert.]

Marshall Herskovitz and Edward Zwick, who count Thirtysomething and My So Called Life among their credits, are getting ready to premiere their newest project, Quarterlife. This one is a little bit different though, as it's not another conventional TV show. Instead, Quarterlife is a web based, advertising supported, series that will air on Myspace. The episodes will be about eight minutes long and follow the lives of a group of college friends that have just recently graduated.
