Background: The Colbert Report () is an American late-night talk and news satire television program hosted by Stephen Colbert that aired four days a week on Comedy Central from October 17, 2005 to December 18, 2014 for 1,447 episodes. The show focused on a fictional anchorman character named Stephen Colbert, played by his real-life namesake. The character, described by Colbert as a "well-intentioned, poorly informed, high-status idiot", is a caricature of televised political pundits. Furthermore, the show satirized conservative personality-driven political talk programs, particularly Fox News's The O'Reilly Factor.
Context: The character first made appearances on the short-lived sketch comedy series The Dana Carvey Show in 1996, described as "a self-important, trench-coated reporter who does on-location stories in a way that suggests his own presence is the real scoop." When The Daily Show ran short on time, a short piece starring Colbert, advertising a fictional program titled The Colbert Report, was added into the program. In these sketches, Colbert began to amplify his character to parody news pundits. Colbert anchored many sketches in his persona, including "Even Stepvhen", in which he debated current issues with fellow correspondent Steve Carell, often devolving into petty name-calling and insults. Colbert and Carell were viewed as potential breakout stars by staff, and when Carell left the series in 2004 to start a US version of The Office, Comedy Central made attempts to keep Colbert at the network. Stewart and Karlin were already looking to expand the Daily Show franchise and their production company, Busboy. The duo supposedly came up with the idea for The Colbert Report after watching coverage of the sexual harassment lawsuit filed against Bill O'Reilly. Colbert met with network president Doug Herzog the day following the 2004 Emmy Awards to first discuss the concept. The one-line pitch Colbert, Karlin and Stewart developed was "Our version of the O'Reilly Factor with Stephen Colbert." Herzog committed to an eight-week tryout period without a pilot. By the time of the 2004 election, the character was fully developed. In creating the character, which is designed to be repellant but entertaining, Colbert conferred with Stewart and Karlin. In expressing his hope that his character not be "an asshole," Stewart remarked, "You're not an asshole. You're an idiot. There's a difference." Head writer Allison Silverman reiterated this trait in a later interview, commenting, "There is an essential innocence to his character." Colbert initially felt the character might not be sustainable in a longer format. Despite this, The Colbert Report was designed as an extension of the satiric goals of The Daily Show, combining it with general silliness and character-driven humor. To make sure there was no overlap in subject matter with The Daily Show, Karlin made trips between the studios during the show's early days to supervise scripts. For the first several years of the program, Colbert made an appearance at the end of each Daily Show in split-screen, having a short discussion with Stewart preceding his show.

Problem: Background: Expose is an American Latin freestyle vocal group. Primarily consisting of lead vocalists Jeanette Jurado, Ann Curless, and Gioia Bruno, the group achieved much of their success between 1984 and 1993, becoming the first group to have four top ten hits on the Billboard Hot 100 chart from its debut album, including the 1988 #1 hit "Seasons Change". In March 2015, Billboard magazine named the group the eighth most-successful girl group of all-time. The group was popular in dance clubs, mainstream Top 40 and adult contemporary charts in the United States.
Context: During the recording of the group's first studio album Exposure, the personnel of the group changed. Reports vary based on the source. According to People magazine, one of the original singers quit while two of the girls were fired midway through the recording of the first album, but according to Billboard, all three were fired. Arista records felt that the three original singers lacked star potential. Martinee states that he made the decision himself to replace the three girls, while Miller maintains it was all their choice, and Jurado confirms that Lorenzo wanted to leave. Shortly thereafter, Casanas pursued a solo career and Lorenzo pursued other ambitions; they were replaced by Jeanette Jurado and Gioia Bruno. Miller began a solo career; she was replaced by Ann Curless. Lorenzo returned to the dance charts with the Vendetta Records releases "I Wanna Know" in 1988, and "Stop Me if I Fall in Love" in 1990, while Laurie Miller released the 12" single "Parallels" on Atlantic Records and a second single "Love is a Natural Magical Thing" on Meet Me In Miami Records. Laurie evolved into a headline performer frequently showcasing her talents on cruises with a more intimate jazz style, and formed her own entertainment company called Xica productions. Casanas later resurfaced as a solo artist (Sandee) and released a solo album, Only Time Will Tell, which garnered the club hits "You're The One", "Love Desire", and the Clivilles & Cole-produced bassline-heavy hit "Notice Me". She continued to tour actively in dance clubs and freestyle shows, until her death on December 15, 2008, of a seizure at the age of 46. All three original members: Casanas, Lorenzo and Miller later contributed vocals on songs on the Miami group Will to Power's eponymous 1988 debut album. Gioia Bruno also provided lead vocals on Will to Power's 2004 album, Spirit Warrior.
