Gossip Girl is an American teen drama series based on the book series of the same name written by Cecily von Ziegesar. The series was created by Josh Schwartz and Stephanie Savage, and premiered on The CW on September 19, 2007. Narrated by the omniscient yet unseen blogger "Gossip Girl", voiced by Kristen Bell, the series revolves around the lives of privileged young adults on Manhattan's Upper East Side in New York City.
The series begins with the return of Serena van der Woodsen (Blake Lively) from a mysterious stay at a boarding school in Cornwall, Connecticut. Blair Waldorf (Leighton Meester), whom creators describe as the queen at the center of their chess game, is a longtime friend and occasional rival of Serena's, and the Queen Bee of Constance Billard School's social scene. The story also follows Chuck Bass (Ed Westwick), the bad boy of the Upper East Side, Nate Archibald (Chace Crawford), Chuck's best friend, and other characters of the turbulent Manhattan scene: Dan Humphrey (Penn Badgley), Nate's friend and Serena's on-again, off-again ex; Vanessa Abrams (Jessica Szohr), Dan's best friend; and Dan's sister, Jenny Humphrey (Taylor Momsen).
Each episode begins and ends with the blog page of the Gossip Girl blog with Serena's picture from the pilot episode. Afterward, a recap of events relevant to the upcoming narrative is shown, which ends again with the blog page, only this time with a picture from other character(s) with a text about a recent event connected with the picture.
The narrator is the Gossip Girl, voiced by Kristen Bell. She begins the recap with the sentence "Gossip Girl here, your one and only source into the scandalous lives of Manhattan's elite," and ends the recap with whispered voices saying "Where has she been?" "Serena" then the voice of Gossip Girl says: "And who am I? That's one secret I'll never tell, you know you love me xoxo Gossip Girl" Each episode usually ends with Gossip Girl saying "You know you love me. xoxo, Gossip Girl."
The first episodes of the first season included the original concept from the books, mainly following the lives of the five teenage characters in their high school years. Serena van der Woodsen (Blake Lively) is often described as the 'it girl'. It is revealed that she has had a scandalous past that continues to haunt her, she is known for her many off-again relationships with the male characters and is known for rebellious drive outs. Dan Humphrey (Penn Badgley), an outsider who becomes a part of the turbulent Manhattan scene, an aspiring writer and fairly straight-arrow guy with a good heart and morals. Blair Waldorf (Leighton Meester) is the beautiful Queen Bee of Constance Billard School's social scene, as well as Serena's best friend and occasional rival. Nate Archibald (Chace Crawford) is the perfect "Golden Boy" of the Upper East Side, always being fought over by the prominent female characters. Chuck Bass (Ed Westwick) serves as the show's antihero, being a womanizer and party lover with a troubled life and past that provide a hidden vulnerable side.
Beside the five regulars cast members mentioned above, three more characters appeared in the pilot episode. Jenny Humphrey (Taylor Momsen) is Dan's younger sister, who desperately tries to become the next Queen Bee, a goal that makes her realize the true values of life; Lily van der Woodsen (Kelly Rutherford) and Dan's father Rufus Humphrey (Matthew Settle).They share a romantic past that follows them throughout the show, and eventually leads to marriage. The Humphrey family is centered upon as they explore life on the 'Upper East side', Dan trying to look after his little sister as she discovers the party scene.
Vanessa Abrams (Jessica Szohr), enters the show in its first season as Dan's past love, and becomes a series regular after the 14th episode. Other characters include Eric van der Woodsen (Connor Paolo) Serena's kind and compassionate brother, who comes out late in the first season and becomes very close with Jenny. Georgina Sparks (Michelle Trachtenberg) is an occasional antagonist in the show, with a recurring role. Carter Baizen (Sebastian Stan) appears as Chuck's enemy with a romantic interest in Serena.
