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, now the 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.

Hilty stars in NBC's upcoming musical drama "SMASH," as the seasoned triple-threat Ivy Lynn, an ensemble performer who has spent years pursuing stardom only to be bumped back into the chorus again and again. A native of Seattle, Hilty moved to New York City after graduating from the prestigious Carnegie Mellon University, and quickly made her Broadway debut as Glinda in "Wicked." She went on to perform the role in both the national tour and in Los Angeles. After receiving rave reviews for her portrayal of Doralee Rhodes in Broadway's "9 to 5: The Musical," Hilty was honored with nominations for "Lead Actress in a Musical" at the Drama Desk Awards, Outer Critics Circle Awards, the Drama League Awards and L.A. Stage Alliance Ovation Awards. She starred in "Two by Two" as part of the reprise series in Los Angeles, opposite Jason Alexander, Steve Weber and Faith Prince. Hilty has also performed with the Cincinnati Symphony and at Feinstein's in New York City.
