Over the last two decades we have reduced the amount of time spent to get many of the items we need. Since we can now order online from our homes we don't have to go out and get them, this frees up a reasonable chunk of time.
Also, over the last 50 or so years we have lost many 3rd places. A 3rd place is where you would spend your time that is not work or home. A bar, community center, an arcade..ect. those were a common place to spend time socializing.
Finally, items like reading and watching TV filled a lot of time. From reading the newspaper to getting the local news. Channel surfing was a big thing for a while. You would cycle through channels until you found something you wanted to watch, you could cycle channels for a while before finding something, so that took up a large chunk of time.
Television was actually fun to watch. Magazines were actually fun to read. Video games were actually fun to play. Hell, playing outside was fun. Playing with toys was fun (even as an adult). Spending time with users on early internet forums was also very fun. Music was much more aesthetically pleasing to listen to (at least the hits of the 00s were, imo). We fidgeted with literally anything we could think of. Pens, rulers, balls (it's not what you think), toys, even our own fingers.
It was really easy to get bored back then too, but at least it was really easy to escape boredom back then.
Magazines were well written, articles were new and fresh. The CNN 24 news cycle brought mass distribution of the news but before that you tuned in for the scheduled news hour you liked
I used to grab anything I could to read when taking a shit. Even reading shampoo bottle labels. Now I'm here typing this mess to you guys as I take a dump.
Let me tell you a tale about downloading erotic jpeg files over 28k modems and stitching them back together, in which the image file was split into pieces, uuencoded and posted on Usenet.
