Slideshow: Rockefeller Center Christmas tree lighting
The Rockefeller Center Christmas tree, a 76-foot Norway Spruce from Shelton, Conn., has been lit with the help of New York City Mayor Michael Bloomberg.
The 75-year-old tree was illuminated by 45,000 multi-colored LED lights in an annual holiday tradition Wednesday night. Topping it off was a 9 1/2-foot-wide Swarovski star.
"Today" show personalities Matt Lauer, Al Roker, Savannah Guthrie and Natalie Morales co-hosted the event, which aired on NBC.
The tree-lighting included live performances from artists such as Mary J. Blige, Mariah Carey, the Goo Goo Dolls, Jewel and Leona Lewis.
The first Christmas tree was set up in 1931 by workers who were building Rockefeller Center. The first tree-lighting ceremony was held in 1933.
