help-understand Milleniums?

My theory, it started with TV. Made humans passive. Heck I remember as a 3 yr old, my favorite time was Saturday morning I'd jump out of bed and plop down in front of the TV and watch The Jetsons. Key word "watch." Back when my Dad grew up in a small town, they had to go outside to entertain themselves by scrounging scrap wood and building things.
