the show a second chance, and it was renewed for the 1983-84 season, which saw none of its nine fall shows being renewed for a second season (one of them, We Got It Made, premiered on Thursdays during its first season, and later was revived a few years later for first-run syndication). NBC decided to move both Family Ties and Buffalo Bill from Wednesdays to Thursdays during the winter of 1984, joining Cheers, Hill Street Blues and Gimme a Break!, with newcomer Night Court joining the lineup during the summer. What marked the beginning of NBC's dominance on Thursday nights was during the 1984-85 season, when the network premiered a new show: The Cosby Show, receiving critical acclaim, with TV Guide listing the series as "TV's biggest hit in the 1980s", adding it "almost single-handedly revived the sitcom genre and NBC's ratings fortunes". The enormous success of Cosby (which became the third-most watched show of the season in the US) also helped the other shows on its Thursday night lineup increase its ratings dramatically, with Family Ties entering the top-ten for the first time; and Cheers and Night Court both entering the top-twenty; while Hill Street Blues remained steadily on the top-thirty. When Cosby debuted, it marked a major turning point for NBC as well, as the network rose to second place at the end of the season; and reach first place at the end of the 1985-86 season, with Cosby being the number-one show in the US, which it managed to stay on that position for four more seasons until 1990. During the late 1980s, other NBC shows-turned-hits on Thursdays includes Cosby spinoff A Different World, Dear John and L.A. Law. However, that dominance during the 1980s, would began to fade by the start of the 1990-91 season, as the strength of ABC Tuesday and Friday night lineups and Fox's decision to move The Simpsons to Thursdays to compete with Cosby contributed in part on it. Cosby slipped down to fifth place, while another NBC show, Cheers, reached number one on the Nielsen ratings for the first time. The 1991-92 and 1992-93 seasons were two of NBC's weakest, as Cheers was the only NBC show inside the top-ten during both seasons; with Cosby and A Different World ratings decreasing considerably; while Wings began to enjoy popularity among viewers on Thursday nights. Cosby ended its run in 1992; while A
