Taylor Swift Performs On Saturday Night Live

On January 10, 2009, Swift made her first musical guest appearance on Saturday Night Live, making her the youngest country singer to appear as a musical guest on the show in its 33-year run.

Swift's show achieved SNL’s highest adult 18-49 rating and overall viewer total since the November election (in 2008). It was tied for the #7 rating of that week among all broadcast and cable entertainment programs on all networks and outscored all its telecasts of last season in 18-49 and total viewers.

Saturday Night Live (SNL) is a weekly late-night sketch comedy and variety show filmed in New York City. It made its debut on October 11, 1975. The show features a regular cast of comedy actors, joined by a guest host and musical act. The show is broadcast live in the Central and Eastern time zones (with a time delay in the Mountain Time Zone and Pacific Time Zone) from Studio 8H at the GE Building in New York's Rockefeller Center.

It was created by Canadian Lorne Michaels, who, excluding seasons 6–10, has been with the show throughout, first as producer and writer and later its executive producer. The show was originally intended to have just six episodes. Currently in its 34th season, SNL is one of the longest-running network programs in American television history. The first episode of the 35th season will air on Saturday, September 26, 2009.

Throughout its history (except for season 7 and other rare exceptions), the show has traditionally begun with a cold open that ends with someone breaking character and proclaiming "Live, from New York, it's Saturday night!"
