proved successful in the 18- to 49-year-old demographic, and the 2011 transfer of Fox's American Idol, regarded as the longest reigning #1 program on U.S. television from 2004 to 2011, into the Thursday timeslot adversely affected NBC's ratings for Thursday primetime programming lineup since that television season. The "Must See TV" slogan reappeared briefly in early 2006 with the addition of two critically acclaimed and ratings-successful comedies, My Name Is Earl and The Office, in an attempt to re-establish a four-sitcom block after the rise and fall of The Apprentice, which was moved to Monday nights. In November 2006, NBC rebranded the Thursday format with a different slogan, "Comedy Night Done Right", and added another two critically acclaimed shows, Scrubs and 30 Rock, to the lineup, forming an entire lineup of comedy series without laugh tracks or the multiple-camera setup common with past "Must See TV" comedies. In January 2011, NBC rebranded the night once again, renaming it "Comedy Night Done Right – All Night", adding a third hour of comedies at 10 p.m. (the network had previously run a three-hour comedy lineup once annually on Thursdays during the late 1990s and early 2000s as a programming stunt). The three-hour comedy block was discontinued in the fall of 2011, when the night reverted to two hours of comedies and one drama and, in 2012, two hours of comedy and the news magazine Rock Center. Change and record ratings lows Prior to the 2013 fall season, NBC cancelled or ended nine of its eleven comedies, including the long-running 30 Rock and The Office, in an effort to broaden its comedy lineup. In May 2013, NBC picked up three family comedies (The Michael J. Fox Show, Sean Saves the World and Welcome to the Family) and rebranded its Thursday night lineup as "NBC's New Family of Comedies" for the fall season. The debut of The Michael J. Fox Show was the lowest-rated Thursday fall comedy series premiere in network history. One week later, the debut of Welcome to the Family became the new record-holder, with Sean Saves the World ranking as the second lowest ever. On October 10, 2013, NBC tied an all-time low on Thursday nights (tied with May 17, 2012), while finishing in fourth place (or combined with programming on Spanish-language network Univision, along with Thursday Night Football on NFL Network and Major League Baseball playoff coverage on TBS, seventh)
