Ratings improved for the summer reruns after the first season. The cast went on various talk shows to try to further promote the series after its first season. By the second season "Cheers" was competitive with CBS's top-rated show "Simon & Simon". With the growing popularity of "Family Ties", which ran in the slot ahead of "Cheers" from January 1984 until "Family Ties" was moved to Sundays in 1987, and the placement of "The Cosby Show" in front of both at the start of their third season (1984), the line-up became a runaway ratings success that NBC eventually dubbed "Must See Thursday". The next season, "Cheers" ratings increased dramatically after Woody Boyd became a regular character as well. The fifth season earned the series the highest rating for the year that it would ever achieve. Although ratings mostly declined each year after that, the show retained a competitive advantage and rose to rank number one for the year for its first and only time in the ninth season. Although ratings and ranking both lost ground in the last two seasons, it still performed well, as it was the only show on NBC during those seasons to be in the top 10. By the end of its final season, the show had a run of eight consecutive seasons in the top ten of the Nielsen ratings; seven of them were in the top five.
