Game$how Marathon is an American television program which aired on CBS from May 31, 2006 to June 29, 2006. It is based on the UK series Ant & Dec's Gameshow Marathon which aired on ITV in 2005. The show features contestants competing in some of television's most historically popular game shows, in a single-elimination format until an ultimate winner is found. Both the UK and US versions featured celebrity contestants. The US version was produced by FremantleMedia North America and Granada America and was hosted by Ricki Lake and announced by Rich Fields. In the US, the series only aired for a single season, while in the UK a second season aired in 2007, this time entitled Gameshow Marathon and hosted by Vernon Kay. This program was recorded at Stage 46, CBS Television City in Los Angeles, CA, USA.

Dinner for Five is a television program in which actor/filmmaker Jon Favreau and a revolving guest list of celebrities eat, drink and talk about life on and off the set and swap stories about projects past and present. The program seats screen legends next to a variety of personalities from film, television, music and comedy, resulting in an unpredictable free-for-all. The program aired on the Independent Film Channel with Favreau the co-Executive Producer with Peter Billingsley. The show format is a spontaneous, open forum for people in the entertainment community. The idea, originally conceived by Favreau, originated from a time when he went out to dinner with colleagues on a film location and exchanged filming anecdotes. Favreau said, "I thought it would be interesting to show people that side of the business". He did not want to present them in a "sensationalized way [that] they're presented in the press, but as normal people". The format featured Favreau and four guests from the entertainment industry in a restaurant with no other diners. They ordered actual food from real menus and were served by authentic waiters. There were no cue cards or previous research on the participants that would have allowed him to orchestrate the conversation and the guests were allowed to talk about whatever they wanted. The show used five cameras with the operators using long lenses so that they could be at least ten feet away from the table and not intrude on the conversation or make the guests self-conscious. The conversations lasted until the film ran out. A 25-minutes episode would be edited from the two-hour dinner.

Newlyweds: Nick and Jessica is a reality television show that was produced and aired by MTV and MuchMusic. It followed the marriage of then husband and wife Nick Lachey and Jessica Simpson. The show first aired in August 2003 and ran three seasons, with 41 episodes in total. The last season started on January 26, 2005, and the last episode aired on March 30, 2005. Simpson and Lachey were married on October 26, 2002 and filed for divorce on December 16, 2005. On June 30, 2006 Jessica and Nick's divorce was finalized. Part of the show's gimmick involved displaying Simpson's naive personality, playing on the popular stereotype of "dumb blondes". Perhaps the most famous example comes from the first episode, in which Simpson, confronted with a can of Chicken of the Sea tuna, asked Nick "Is this chicken, what I have, or is this fish? I know it's tuna, but it says [sic] 'Chicken... by the Sea'."

Storybook Squares is a short-lived Saturday morning version of Hollywood Squares for children. The primary difference, apart from having children as contestants, was that it featured celebrities in costume as well-known fictional characters and some as historical figures. As with the adult version, Peter Marshall was host and Kenny Williams was announcer; Williams read the characters' names off a scroll as "The Guardian of the Gate", a role similar to his "Town Crier" on Video Village. The series originally ran on NBC from January 4 to April 19, 1969, with repeats airing until August 30.
