Canada's Worst Handyman is a Canadian television series broadcast on Discovery Channel.
 The show is produced by Proper Television, and shares its production with "Canada's Worst Driver", including executive producer Guy O'Sullivan and host Andrew Younghusband.
 The series is based on a one-off 2004 episode of the "Britain's Worst" series, titled "Britain's Worst DIYer".
 Like sister series "Canada's Worst Driver", there have been similar adaptations in other English-speaking countries, in the US in 2011, with "America's 10 Worst DIYers", in Britain with a "Britain's Worst" 2005 spin-off series, "Britain's Worst DIYer".
 Six seasons of the show have been completed.
I Survived... is a documentary television series produced by NHNZ that airs on Lifetime Movie Network.
 The series premiered on March 24, 2008 and in the past has aired new episodes Sunday nights.
 The show currently airs on Friday evenings at 8 PM Eastern Time followed by sister series "I Survived... and Back" (in which people share their near death experiences).
 The show allows survivors to explain – in their own words – how they overcame life-threatening circumstances without dramatic reenactments.
 Most episodes feature three separate stories involving kidnapping or getting stranded in a remote location; however, some only feature two.

 The series was nominated for the GLAAD Media Award for Outstanding TV Movie or Limited Series.
Hangin' with Mr. Cooper is an American television sitcom that originally aired on ABC from September 22, 1992 to August 30, 1997, starring Mark Curry and Holly Robinson.

 The show originally aired on Tuesdays in prime time after sister series "Full House" (which was also created by Jeff Franklin and set in the San Francisco Bay Area).
 The show found its niche as an addition to the "TGIF" Friday night lineup on ABC, and was part of the lineup from September 1993 to May 1996 (spanning the show's second, third and fourth seasons; airing in-between "Step By Step" and the news magazine series "20/20"), before moving to Saturdays for its fifth and final season.
VR Troopers (Virtual Reality Troopers) is a syndicated live action superhero-adventure television series produced and distributed by Saban Entertainment from 1994 to 1996.

 "VR Troopers" was the first official "sister series" to "Mighty Morphin' Power Rangers".
 Much like it, this was an Americanization of a Japanese tokusatsu children's program series by Toei.
 The series is a co-production of Toei Company and Cyberprod.
