The Ed Wynn Show was an American comedy/variety show originally broadcast from September 22, 1949–July 4, 1950 on the CBS Television Network.
 Comedian and former vaudevillian Ed Wynn was the star of the program.
 39 episodes were produced and broadcast live from Hollywood, making "The Ed Wynn Show" the first program to do so, and transmitted via kinescope to New York.
Hot Property is a Channel 5 show originally broadcast from 1997 to 1998 and hosted by Sandy Mitchell.
 It was then revived from 5 November 2001 to 11 July 2003 in two formats; originally hosted by Tris Payne in 2001 but then replaced by Alice Beer from 2002, when the series was retooled into a game show.
Enough Rope with Andrew Denton (often shortened to Enough Rope) is a television interview show originally broadcast on ABC1 in Australia.
 The title of the show came from the phrase "give someone enough rope and they'll hang themselves".
Take Your Pick!
 was a United Kingdom game show originally broadcast by Radio Luxembourg in the early 1950s.
 The show was moved to television in 1955 with the launch of ITV, where it continued until 1968.
 As it was the first game show broadcast on commercial television in the UK (and the BBC), monetary prizes were not offered to its participants.
 It was also, by default, the first British game show to offer cash prizes.
 The programme was later revived from 24 February 1992 to 28 August 1998.
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.
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.
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.

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 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.

 The programme returned after a three-year break, from 25 May 2009 to 9 March 2012.
 In early 2013, the show went into hiatus again and was replaced by 2 new shows, "Brendan's Magical Mystery Tour" and "Brendan's Love Cruise".
 However, in September 2013, Channel 4 announced that they had renewed "Coach Trip" for another series in 2014 which has now aired.
 On 9 April 2014, a further four series were announced following the success of the ninth series in early 2014.
