The Golden Girls: Their Greatest Moments is a 2003 American television special celebrating the 1985–1992 sitcom "The Golden Girls" starring Bea Arthur, Rue McClanahan, and Betty White.
 It originally aired on Lifetime on June 2, 2003.
Hollywood on Television was a five-and-a-half-hour, six-day-a-week live television talk show starring newcomer Betty White and radio disc jockey Al Jarvis that ran from 1949 to 1953.
 When Jarvis left the show in 1951, film star Eddie Albert took his place and co-hosted with White for six months until thirty-three and a half hours of live ad-lib television per week, featuring just the two of them, took its toll and he also resigned.
 White was then hosting the show alone, and is believed to have been the first female television talk show host as a result.
 After a period of White talking directly into the camera lens for hours at a stretch, the show began accepting guests to interact with her as well as gradually incorporating scripts and sketches.
 Similarly to Jackie Gleason's "Honeymooners" sketches on the Dumont Network during the same era, recurring sketches involving White as a housewife named Elizabeth caught on with the viewers to the point that expanding the sketches into a half-hour sitcom appeared to be the obvious next step.
 Series pianist George Tibbles began writing the sketches.
 Studio producer Don Fedderson, Tibbles and White formed a production company called "Bandy Productions," named after Betty White's dog Bandit, and White changed over to a half hour sitcom format based on the Elizabeth sketches entitled "Life With Elizabeth", which ran in syndication for two years and sixty-five episodes.
 Across the decades, White would use the skills she had honed on "Hollywood on Television" by hosting her own talk show in 1954 and subsequent variety series as well as starring in numerous sitcoms, including "Date with the Angels", "The Mary Tyler Moore Show", "The Betty White Show", "The Golden Girls", "The Golden Palace" and "Hot in Cleveland", as well as hosting the 2012 prank show "Betty White's Off Their Rockers", which began airing 63 years after the premiere of "Hollywood on Television".
Ladies Man is an American television sitcom series starring Alfred Molina as husband, father, son, ex-husband and son-in-law who lives with a number of women under one roof.
 The show was first broadcast on September 20, 1999, and lasted for two seasons on CBS until June 27, 2001.
 The series co-starred Betty White and is perhaps most memorable for reuniting White and her "Golden Girls" co-stars Rue McClanahan and Estelle Getty in one of the later episodes.
Betty White's Off Their Rockers is an American comedy television series launched in 2012, that broadcast on NBC for its first two seasons and Lifetime beginning with the third.
 The series is hosted by Betty White, and is based on the Belgian television format "Benidorm Bastards".
Rose Nylund (née Lindström) is a fictional character featured on the popular 1980s situation comedy "The Golden Girls", and its spin-off "The Golden Palace".
 She was portrayed by Betty White for 8 years, totaling 208 episodes.
 Rose was originally supposed to be played by Rue McClanahan, whereas Blanche Devereaux, one of Rose's roommates, was to be played by White.
 However, Jay Sandrich, the director of the show, suggested that Betty and Rue switch parts.
 He felt that Betty would be a better fit for Rose because she had already played Sue Ann Nivens in the television show "The Mary Tyler Moore Show", which is similar to the character of Blanche Devereaux.
 In a January 2017 interview with Katie Couric, White stated she jumped at the opportunity to take the role of Rose, noting she loved the character and describing Rose as "so innocent, not the brightest nickel in the drawer, but funny."
"Stone Mountain" is the third episode of the fourth season of the American television comedy series "30 Rock", and the 61st overall episode of the series.
 The episode was written by co-executive producer John Riggi and directed by series producer Don Scardino.
 It originally aired on the National Broadcasting Company (NBC) network in the United States on October 29, 2009.
 Guest stars in "Stone Mountain" include Jeff Dunham and Bubba J, Jimmy Fallon, Blaine Horton, and Betty White.
