Televisionland heads into December with holiday shows and some that herald the end of the year and century.

On Wednesday, NBC kicks off the month with "Christmas in Rockefeller Center" at 8, with hosts Matt Lauer and Brandy, plus Britney Spears, 'N Sync, Enrique Iglesias, Rosemary Clooney, Scott Hamilton, cast of the stage's "Saturday Night Fever" and the Radio City Music Hall Rockettes. That's followed by "Garth Brooks & the Magic of Christmas" at 9, with Tony Bennett, Natalie Cole, Trisha Yearwood and a 32-piece big band playing Christmas tunes.

CBS offers the old, beloved chestnuts "Rudolph the Red-Nosed Reindeer" (Wednesday at 8), "The Year Without a Santa Claus" (Thursday at 8) and "A Charlie Brown Christmas" (Friday at 8). Two new treats air Friday: at 8:30, "Snowden's Christmas," featuring foam latex puppets and the voices of Peter MacNicol, Kathy Najimy, Edward Asner and Michael McKean; and at 9, "The Nuttiest Nutcracker," with Phyllis Diller as the Sugar Plum Fairy, James Belushi as the Evil Mouse King and Cheech Marin as Mac, the macadamia nut. On Saturday at 8, Amy Grant's holiday music special features Tony Bennett, Cece Winans and 98 Degrees.

And Thursday, some of the century's top athletes -- including Muhammad Ali -- will be honored at "Sports Illustrated's 20th Century Sports Awards."
