Think about other entertainment option in the 50s-80s.
What was your tv options? Number of channels? Channels after midnight?
Game systems and options available? Atari, nintendo, computer etc.
Now the internet as you mentioned.
More things for people to do. Interesting with the article is the other social norms people use to take part in that are also suffering.
"Putnam notes the aggregate loss in membership and number of volunteers in many existing civic organizations such as religious groups (Knights of Columbus, B'nai Brith, etc.), labor unions, Parent-Teacher Association, Federation of Women's Clubs, League of Women Voters, military veterans' organizations, volunteers with Boy Scouts and the Red Cross, and fraternal organizations (Lions Clubs, Benevolent and Protective Order of Elks, United States Junior Chamber, Freemasonry, Rotary, Kiwanis, etc.).[1] To illustrate why the decline in Americans' membership in social organizations is problematic to democracy, Putnam uses bowling as an example. Although the number of people who bowl has increased in the last 20 years, the number of people who bowl in leagues has decreased. If people bowl alone, they do not participate in social interaction and civic discussions that might occur in a league environment.[1]"
