No, but it boils down to what one is referring to with "living room".
A very popular trend these days is an open concept home where the "living room" is part of a large open space that includes the dining room and kitchen. These homes may or may not have a separate sitting room such as family or rec room.
With respect to homes not open concept (despite the popularity of open concept, many people still prefer separate rooms), the living room approach is mixed. Some people still include both a formal living room as well as an informal living space such as family room.
Here's my take and my preference. I like two "living rooms" especially having young kids. One serves as a kid-oriented space which over time will evolve into a family room. The other serves as the adult-oriented space. Our home (built in 1984) has both living room and family room. My wife and I use the "living room" every day. It's not some space we dress up only for company. It's an integral part of our home.
This issue arises largely due to the growth in open concept, which has a "living room" but it's not as formal as the old-school separate formal living rooms because they're used daily and are a part of the main living space. Smaller homes such as condos, townhomes and smaller detached homes do not have a separate living room space.
Here's the trend trajectory of "open concept living rooms" over past five years:
