Question:  From 2006 to 2008, NBC's studio show originally broadcast out of the rink of a complex that covers how many acres?

From 2006 to 2008, NBC's studio show originally broadcast out of the rink at New York's Rockefeller Center, at the foot of NBC's offices during January and February.  This allowed the on-air talent, including commentators for "NHL on NBC", and their guests (often ex-players and youth hockey teams) to demonstrate plays and hockey skills.  From April onwards, and during inclement weather, the studio show moved to Studio 8G inside the GE Building, where NBC produces its "Football Night in America" program.  For the Stanley Cup Finals, the show was broadcast on location. <SEP> Rockefeller Center is a large complex consisting of 19 high-rise commercial buildings covering 22 acre between 48th and 51st Streets in New York City.  Commissioned by the Rockefeller family, it is located in the center of Midtown Manhattan, spanning the area between Fifth Avenue and Sixth Avenue. <SEP> The Preserve at Sharp Mountain (also called The Sharp Mountain Preserve) is a nature-based community located near Jasper, Georgia in Pickens County.  It is one of three mountain communities in Pickens County, and the only one dedicated to maintaining its natural amenities.  There are 12 mi of paved roads running through the community, but the population density is intentionally low (approximately 300 lots over 1600 acre ranging in size from a minimum of 3 acre to a maximum of 37 acres.)  The Preserve at Sharp Mountain was named the "Best Community for Outdoor Lovers" by Pinnacle Living magazine, Unlike many planned communities, the Preserve at Sharp Mountain does not have swimming pools and tennis courts with club houses or golf courses.  Instead, the Preserve at Sharp Mountain offers many acres of green space, hiking and nature trails, a nature pavilion, waterfalls, a bird sanctuary, a butterfly garden and various nature parks.  The community is gated to restrict use of its 12 mi of privately owned roads to those living in the community.  The Preserve at Sharp Mountain was developed by Four Seasons originally, which later became Naterra Land.  Naterra's stated goal in all of its projects is "to better connect people with nature."  Naterra Land sold out all of its inventory in the Preserve, and control of the community is now governed by a Property Owners' Association (POA).  In 2011, the Preserve Association switched from being an HOA (Home Owners' Association) to being a POA (Property Owners' Association), each being viewed differently under Georgia law.  In 2008 the Preserve became a recognized member of the national Firewise communities program and is one of the 13 in Georgia. <SEP> Football Night in America is an American pre-game show that is broadcast on NBC, preceding its broadcasts of Sunday night and Wild Card Saturday National Football League (NFL) games.  The program debuted on September 10, 2006, when the network inaugurated its Sunday prime time game package.  The 80-minute program airs live at 7:00 p.m. Eastern Time, and is broadcast from Studio 1 at NBC Sports Headquarters in Stamford, Connecticut.  Prior to 2012, "Football Night in America" originally broadcast from the GE Building in New York City, first out of Studio 8G from 2006 to 2012 and in 2013, from Studio 8H, where "Saturday Night Live" is also taped.
