Must-See Math: The 80s vs. 90s Sitcoms That Owned Prime Time

Part 1 of 2. This one is about the shows. Next week is about the songs.

Somewhere in the early 90s, the remote control became the villain. A full minute of theme song is a full minute for your thumb to wander. In the summer of 1994, ABC’s entertainment president, Ted Harbert, told Variety he was asking producers to drop the traditional opening titles from new shows. He called them “an antiquated practice.” He also admitted the research behind that was inconclusive, which is my favorite part.

So I wanted to know: did the theme song ever matter? Did a great opening make a great show, or did a great show make us remember the opening? Before I could answer that, I had to answer a more boring question. Which sitcoms actually owned prime time? That’s this post.

The rules

Who made the cut

More 90s sitcoms cracked a top 30. The cut kept the same share of each.

Icon array of small TV sets. 1980s: 35 sitcoms reached a season's top 30, and the top 7 made the cut. 1990s: 47 sitcoms reached a season's top 30, and the top 10 made the cut.
Sitcoms that aired mainly 8–10 p.m. ET on ABC, CBS, NBC, Fox (from 1987), The WB and UPN (from 1995) and reached a season’s top 30, counted in the decade of their first full season. Source: Nielsen season rankings via Wikipedia (Brooks & Marsh).

I kept it to scripted sitcoms on the broadcast networks between 8 and 10 p.m. Eastern. That’s ABC, CBS and NBC, plus Fox from 1987 and The WB and UPN from 1995. The 80s run from the 1980–81 season through 1989–90, and the 90s from 1990–91 through 1999–2000.

Shows that straddle two decades were the headache. I gave each one to the decade of its first real season, meaning its first season of 13 or more episodes. That makes Seinfeld a 90s show, which it obviously is. Its 1989–90 “season” was a four-episode tryout. Wings goes to the 90s too.

Nielsen’s published season rankings only go 30 deep, so my pool is every qualifying sitcom that cracked a season’s top 30 at least once. That’s 35 sitcoms from the 80s and 47 from the 90s. From each pool I kept the top 20% by best single season: 7 shows from the 80s and 10 from the 90s. Twenty percent of 47 is 9.4, which rounds to 9, but The Single Guy and Room for Two tied at a 16.7 for the last spot, so both stay.

One honest gap. A few of the old 80s lists I worked from were cut off at the bottom, so a couple of low-ranked 80s shows may be missing from the pool. Nobody missing would outrank the seven that made it.

The top 20%, by best season

Five of the seven 80s shows peaked in the same season.

Horizontal bar chart of peak season ratings. 1980s: The Cosby Show 34.9 (#1, 1986–87), Family Ties 32.7 (#2, 1986–87), Cheers 27.2 (#3, 1986–87), A Different World 25.0 (#2, 1987–88), The Golden Girls 24.5 (#5, 1986–87), Roseanne 23.8 (#2, 1988–89), Night Court 23.2 (#7, 1986–87). 1990s: Seinfeld 21.7 (#1, 1997–98), Home Improvement 20.4 (#2, 1993–94), Friends 18.7 (#3, 1995–96), Grace Under Fire 18.6 (#4, 1994–95), Caroline in the City 18.0 (#4, 1995–96), Suddenly Susan 17.0 (#3, 1996–97), Frasier 16.8 (#7, 1993–94), The Naked Truth 16.8 (#4 tie, 1996–97), The Single Guy 16.7 (#6, 1995–96), Room for Two 16.7 (#10 tie, 1991–92).

Six of the seven 80s shows were on NBC, and five of them peaked in the same season, 1986–87. That season, NBC sitcoms held five of the top seven spots in all of prime time, not just among sitcoms: The Cosby Show at #1, Family Ties at #2, Cheers at #3, The Golden Girls at #5 and Night Court at #7. Four of those aired on the same night, Thursday, back to back.

I know it’s unpopular to say these days, but I loved The Cosby Show

The top of the 80s list also has a tie. In 1989–90, Roseanne and The Cosby Show tied for #1 with a 23.1. Roseanne only had two seasons inside the 80s and still made the cut.

The 90s: three anchors and the neighbors

Same shows, by best rank

On rank, the two decades look a lot alike.

Dot plot of each show's best season rank, with the top four shaded. 1980s, 6 of 7 reached the top four: The Cosby Show #1, Roseanne #1, Family Ties #2, A Different World #2, Cheers #3, The Golden Girls #4, Night Court #7. 1990s, 8 of 10 reached the top four: Seinfeld #1, Home Improvement #2, Friends #2, Suddenly Susan #3, Frasier #3, Grace Under Fire #4, Caroline in the City #4, The Naked Truth #4, The Single Guy #6, Room for Two #10.

The 90s list starts where you’d expect: Seinfeld, Home Improvement, Friends. Then it gets interesting. Grace Under Fire, Caroline in the City, Suddenly Susan, Frasier, The Naked Truth, The Single Guy and Room for Two round out the ten.

Real estate explains a lot of that. The Single Guy sat between Friends and Seinfeld. Caroline in the City and Suddenly Susan each held the 9:30 slot right after Seinfeld. Room for Two followed Roseanne. Seven of the ten spent time on NBC’s Thursday night. Think of a strip mall: the anchor stores bring the traffic, and the shop wedged between them does great business for a couple of years.

Now look at rank instead of rating. Six of the seven 80s shows reached the top four in at least one season. Eight of the ten 90s shows did too. On rank, the elites of both decades look like the same club.

Two near misses, since somebody will ask. Veronica’s Closet missed the 90s cut by one-tenth of a rating point, with a 16.6 and a #3 finish in 1997–98. Everybody Loves Raymond didn’t come close inside the 90s. Its best 90s season was an 11.4 at #12, and its giant years came after 2000.

Points vs. people

Homes, not points

Two #1 shows, eleven seasons apart.

Two bars showing homes watching as a share of all TV households. The Cosby Show, #1 in 1986–87 with a 34.9 rating: 30.5 million homes of 87.4 million. Seinfeld, #1 in 1997–98 with a 21.7 rating: 21.3 million homes of 98.0 million.

Here’s where I had to fix my own thinking. The 80s shows were bigger. Actually, no, that’s not right. The 80s shows had bigger ratings, and that isn’t the same thing. A rating is a percentage, the share of all TV homes tuned in, and the number of TV homes kept growing.

The Cosby Show was #1 in 1986–87 with a 34.9. That was about 30.5 million homes out of 87.4 million with a TV. Seinfeld was #1 in 1997–98 with a 21.7, about 21.3 million homes out of 98.0 million. Both were #1.

Between those two seasons, the country added 10.6 million TV homes, and the #1 show reached 9.2 million fewer of them. Cable cut into the networks’ share, so 90s ratings ran lower across the board, even for the hits. A percentage is only as honest as the thing it’s a percentage of. From here on, I lean on rank.

The hand-off

Ratings, season by season

Cheers hands off to Seinfeld, and nobody gets back to 1986–87.

Line chart of season ratings from 1984–85 to 1999–2000 for the 17 top shows, with Cheers and Seinfeld highlighted. Cheers peaks at 27.2 in 1986–87 and ends at 16.1 in 1992–93. Seinfeld enters the top 30 in 1992–93 at 13.7 and finishes at 21.7, #1, in 1997–98. The Cosby Show's 34.9 in 1986–87 is the highest point on the chart.

Two lines tell the story. Cheers peaked with a 27.2 in 1986–87 and eased down from there. Its last season, 1992–93, was Seinfeld’s first in the top 30. Seinfeld ended up in Cheers’ old Thursday 9:00 slot and finished its final season, 1997–98, at #1 with a 21.7.

No season in the 90s on this chart beat that 21.7. In 1986–87 alone, five 80s shows did. Two things are true at once: the 80s had the bigger crowds, and the 90s had the same kind of dominance over a smaller slice of a bigger country.

Next week: the music

That’s the field. Seventeen shows, two decades and one very crowded Thursday. Next week I get to the question I actually started with: did a great theme song make a great show? I built a catchiness score to find out, and the scatterplot did not cooperate.


Notes and sources. Ratings are Nielsen household ratings for each regular season. Small samples: 7 shows and 10 shows.
