For one thing, I’m not sure it matters that much. A lot of the shows you mentioned are getting very close to the ensemble-cast level - yeah, there’s a main character that you can ‘pick out’ based on the title, but also a lot of other people who really aren’t just supporting cast, but PART OF the cast, if you see the distinction that I’m making. Lead characters don’t seem to matter as much as they once did, to me.
But, out of curiosity, let’s go down the 2009-2010 US tv schedule and see what the breakdown comes out as:
Sunday - Fox is the only network airing half-hour sitcoms this night.
Brothers: Not familiar with it, but from the title and the Wikipedia summary, obviously male lead characters.
'Til Death: Husband and wife appear to share top billing on this one. Draw
The Simpsons: Simpson family is an ensemble. Bart and Homer still grab a little more attention, but I’m not giving this one to the guys either.
The Cleveland show: Cleveland Brown (and Cleveland junior) give us one more for the fellas
Family Guy: Yeah, okay, Peter’s the lead and title character
American Dad: Don’t even need to comment.
Sons of Tucson: Also seems to focus around guys
Sunday totals: 5 male, 0 female, 2 balanced
Monday - CBS schedule is the one with sitcoms this time.
How I met your mother: Tough one to call, definitely a strong ensemble cast with talented women, but based on the title, the premise, and the narrator, Ted is supposed to be the lead. 1 for the guys.
Accidentally on purpose: Clearly a Jenna Elfman vehicle, so despite no real clues in the title I’m letting the ladies have their first one!
Two and a half men: Yeah, this one is for the boys.
Big bang theory: Again a somewhat tough call, but I’ll take the point that Leonard/Sheldon are the leads, with Penny, Howard, and Raj as supporting cast. Guys take it away.
Monday totals: 3 male, 1 female, 0 balanced.
Tuesday is ABC’s night for sitcoms, at least in the midseason
Scrubs: Ensemble… but JD is central. Male
Better of Ted: Ted. Male
Tuesday totals: 2 male, 0 female, 0 balanced.
Wednesday - for the first time more than one schedule has sitcoms on, both ABC and CBS
Hank: Kelsey Grammar vehicle. (And male lead character in the title.) Male
The new adventures of old Christine: Female
The Middle: Tough call, no obvious cues in the title, and the synopsis says it features the whole family. But the Mom is mentioned first, and is played by someone I recognize, so I’m saying female.
Gary unmarried: Guy
Modern family: This one I’m going to list as a mixed ensemble, though you might stretch that Jay is the connecting thread. Even
Cougar town: Courtney is the Cougar. Female
Wednesday totals: 2 male, 3 female, 1 balanced.
I’ll finish doing the week in my next post.
