The series, starring Lauren Graham and Alexis Bledel as mother and daughter, has become one of the WB's top shows since it debuted in the fall of 2000, averaging about 4.7 million viewers a week (including repeats).
Amy Sherman-Palladino, who created "Gilmore Girls," gets the credit for its quirky comedy-style rapid banter.
Sherman-Palladino is "a gifted writer with one of the most unique voices on television, not to mention a truly frightening collection of silly hats," said Jordan Levin, co-chief executive officer of The WB.
The show, which airs on Tuesday nights, is going through a transition this year as Rory (Bledel) leaves her hometown of Stars Hollow, Conn., for Yale University.
