Why is Modern Family about "modern" familes?

And the building they live in has multiple apartments. For the longest time I though the whole thing was their house; until that episode where they thought James Marsden had moved into one of the other apartments (& he was actually squatting in Lily’s playhouse).

That would be a great title for the show, and even catchier.

You need to pay better attention to the title cards when you’re watching The Culdesac Crew.
