The makeup of the family itself has changed. Look at the popular program Modern Family. There are three kinds of families emphasized: the "normal" mom and dad and three children; the divorced couple (which is a variation in that the husband is a much older man); the gay couple adopting children. The point of the program is that if people love each other no matter who is involved it can be called a family. Technology has opened up the gate for the various forms of families to be accepted.
The idea of family in the past was the family doing everything together. Eating, playing, worshipping--that was the way a family worked. You sat down at the table, ate, and talked about your day. Of course, that is an idea long gone. Occasionally, something happens like the Olympics and people, i.e., families begin to have a topic to talk about together. That makes the media worth it.
