The lineup for NBC's annual Christmas special features Mariah Carey, Kelly Clarkson, Mary J. Blige, the Goo Goo Dolls, Jewel, plus all of your favorite NBC personalities like Matt Lauer, Al Roker and Natalie Morales.

The 81st annual holiday extravaganza will feature a 76-foot Norway Spruce that is 47 feet in diameter and weighs approximately 12 tons. The tree is estimated to be about 75 years old. More than 45,000 energy-efficient multi-colored LED lights will be strung to decorate the tree, topped with a 9 ½ foot wide LED-lit Swarovski crystal star.

The tradition of the Rockefeller Christmas tree dates back to the Great Depression. First erected in 1933, the inaugural tree was decked with 700 lights and placed in front of the then eight-month-old RCA Building (the current GE Building). The Christmas tree gathering was enhanced in 1936 with the opening of the Rockefeller Plaza outdoor ice-skating pond. NBC-TV televised the tree lighting for the first time in 1951 on “The Kate Smith Show” and as part of the nationwide “Howdy Doody” television show from 1953-55.

Prior to this year's primetime telecast, an additional live hour of the special (7-8 p.m. ET) will be broadcast by the following NBC stations: WNBC/New York; WCAU/Philadelphia; KSNV/Las Vegas; WBBH/Fort Myers, Fla.; KHNL/Honolulu, Hawaii; WNWO/Toledo, Ohio; WTWC/Tallahassee, Fla.; WVIR/Charlottesville, Va., WETM/Elmira, N.Y.; WGBC/Meridian, Miss.; KHBC/Hilo, Hawaii; and KOGG/Wailuku, Hawaii.

"Christmas in Rockefeller Center" is produced by Brad Lachman Productions with Lachman serving as executive producer. Bill Bracken will produce.
