NBC's 30 Rock began its 4th season tonight at 8:30.
Liz, Jack, and Tracy are all back on the set of The Girlie Show with Tracy Jordan, a popular comedy show for NBC. Liz Lemon, played by Tina Fey, is the head writer for the show, and is constantly running around the set while dealing with problems from Jordan (Tracy Morgan) and her boss, Jack Donaghy (Alec Baldwin).
Other main characters include Jenna, one of TGS's stars, Kenneth, an NBC page, Pete, another writer, and Frank, a goofy, truck-hat-wearing writer.
The first 3 seasons have been filled with various storylines, from Jack trying to find his father to Liz's never-ending attempt to find love to Devin's (Jack's nemesis) attempt to take over NBC.
Guest appearances have been made by the beautiful Salma Hayek, Jon Hamm (of Mad Men fame), and Edie Falco (Sopranos).
30 Rock consistently has blatant product placement in its episodes, often touting Snapple, GE, or something else. While product placement is nothing new, the way the show does it is pretty humorous.
The show has been incredibly entertaining from the start, garnering strong reviews from critics, but hasn't really been able to attract a large amount of fans in the grand scheme of things. The Academy seems to like the show, as it is regularly nominated for a bunch of awards.
I've often met people who either love the show or can't stand it. Personally, I think it's way funnier than The Office, and hopefully, people will stay tuned in to NBC after watching The Office to see 30 Rock.
