Problem: Background: The Jay Leno Show is an American talk show created by and starring Jay Leno. Premiering on NBC on September 14, 2009, the program aired on weeknights at 10:00 p.m. ET/PT through February 9, 2010. The program was modeled upon the format of a late night talk show--specifically, Jay Leno's incarnation of The Tonight Show, opening with a comedic monologue, followed by interviews with celebrity guests and other comedy segments. Sketches from The Tonight Show (including Headlines and Jaywalking) were carried over to The Jay Leno Show, along with new sketches.
Context: NBC became the first large United States network to broadcast the same show every weekday during prime time since ABC's Who Wants to Be a Millionaire? marathons in 1999 and only the second since DuMont aired Captain Video and His Video Rangers from 1949 to 1955. More recently, the upstart MyNetwork TV had attempted, upon its launch in 2006, to air the same telenovelas every night of the week, a programming strategy that proved to be very unsuccessful. NBC's executives called the decision "a transformational moment in the history of broadcasting" and "in effect, launching five shows." An industry observer said that Leno, "in all my years, is the biggest risk a network has ever taken." According to former NBC president Fred Silverman, "If the Leno Show works, it will be the most significant thing to happen in broadcast television in the last decade."  Although NBC had not developed a new hit show at 10 pm in years, industry executives criticized the network for abandoning a history of airing quality dramas at that hour such as Hill Street Blues, St. Elsewhere, and ER, which made NBC "the gold standard for sophisticated programming . . . the No. 1 network for affluent and well-educated young viewers" during the 1980s and 1990s. In addition, critics predicted that the decision would hurt NBC by undermining a reputation built on successful scripted shows. Other networks believed NBC's decision created an opportunity, and planned their 2009-2010 schedules accordingly. For example, the show competed with The Mentalist, CSI: Miami, CSI: NY, and Numb3rs, four of television's most popular series, on CBS (the first of those four series was moved to 10:00 PM to directly compete with Leno's show, and significantly improved the ratings for that timeslot compared to its predecessor). Leno was also not easily sold overseas.  The January 29, 2010 issue of Entertainment Weekly listed the show at the top of a list of the 50 Biggest Bombs in television history. The comment made by the network executives about "launching five shows" was ultimately transformed into the joke that its removal was like "cancelling five shows". TV Guide similarly listed the show as the biggest blunder in television history in its November 1, 2010 edition.
Question: Did Leno replace another talk show?

Problem: Background: Sonny & Cher were an American pop music duo, actors, singers and entertainers made up of husband-and-wife Sonny and Cher Bono in the 1960s and 1970s. The couple started their career in the mid-1960s as R&B backing singers for record producer Phil Spector. The pair first achieved fame with two hit songs in 1965, "Baby Don't Go" and "I Got You Babe". Signing with Atco/Atlantic Records, they released three studio albums in the late 1960s, as well as the soundtrack recordings for two unsuccessful movies, Good Times and Chastity, with Cher contributing vocals to one cut, "Chastity's Song (Band of Thieves)" .
Context: In 1967 Sonny and Cher released their third album, In Case You're In Love. It peaked at number 45 in the U.S. charts. It contained two hit singles, both written by Bono, "The Beat Goes On" (No. 6 on the Billboard Hot 100) and "Little Man" (No. 21 on the Billboard Hot 100), that peaked at the number one in five European countries.  In an attempt to capitalize on the duo's initial success, Bono speedily arranged a film project for the duo to star in. But the 1967 feature, Good Times, was a major bomb, despite the efforts of fledgling director William Friedkin and co-star George Sanders. After Good Times flopped in 1968, Columbia Pictures immediately sold rights to their intended follow-up film Speedway to MGM. The couple were replaced by Elvis Presley and Nancy Sinatra. In 1969, another film, Chastity, starring Cher, written and produced by Sonny, was also a commercial bomb.  Sonny and Cher's career had stalled by 1968 as album sales quickly dried up. Their gentle, easy-listening pop sound and drug-free life had become unpopular in an era increasingly consumed with the psychedelic rock of the evolving landscape of American pop culture during the late 1960s.  Bono decided to forge ahead, carving a new career for the duo in Las Vegas resorts, where they sharpened their public persona with Cher as the wise-cracking singer, and Bono as the good-natured recipient of her insults. In reality, Bono controlled every aspect of their act, from the musical arrangements to the joke-writing. While success was slow to come, their luck improved when network TV talent scouts attended a show, noting their potential appeal for a variety series.  Sonny and Cher also welcomed their first child, Chastity Sun Bono, born on March 4, 1969.
Question: What kind of woes did their career have during this time?
