What was the most popular sitcom in the 80's,90's and between the 90's-00's?

1980's - Cheers 1990's -Seinfeld or Friends between 90's and 00's - Friends or 2 1/2 Men

90s-00s = Friends

Friends or Seinfeld for the 90s-00s no idea for the 80s Just a guess

According to several sources: the 1980s: The Cosby Show (at one point, 25% of households would watch it) the 1990s: Cheers (ended in 1993) the 00's: Can't find anything on this, but I would say friends in the early half of the 00's and, according to Nielsen data, it is now 2 and a half men!

Beverly Hills 90210, Cosby Show, Cheers, Seinfeld, Melrose Place

Not sure of a lot, but "The Fresh Prince of Bel-Air", "Beverly Hills 9210", and "I love Lucy" were extremely popular.

Neighbours (Aussie sitcom) started in the 80's and its still going.

In the 80's, it was probably M*A*S*H and Family Ties. In the 90's, possibly Seinfeld and Beverly Hills 90210? The 2000's....hmm...possibly Grey's Anatomy or The Office?

The Cosby show had the 80's, along with Full House, Cheers, etc. Between the 90's & 00? I would say Seinfeld, Friends, etc.
