I believe people socialized far more in person. Many organizations thrived during this period, for example the Elks, the Knights of Columbus, and the Masons. People also socialized through their churches and temples far more, and, as one response pointed out, families spent time together, playing board games, listening to the radio, singing songs, and playing cards. I would guess that this was true in many areas through the 1950's. While I embrace all that our age has to offer, I do think that the emphasis today on on-line socialization, in spite of having expanded our social opportunities, has harmed our ability to socialize in person and to play nicely with others.
