I don't think how kids spend their time has changed much.
Yeah, everyone has a computer and internet now.
But every day in my neighborhood from the time school gets out until dark, there are tons of kids playing outside. Riding bikes, scooters, skateboards, playing basketball, kickball, etc. My kids spend just as much time playing outside as I ever did.
I bought a C64 in 1982 and it seemed like everyone I knew had one. So gaming was very big even then.
Life before the internet:
People got together physically at weekly user group meetings to copy software instead of dl'ing from Kazaa.
You had to spend hours in a library to do any research instead of minutes on the net.
If you needed information, it involved looking up a phone number in a phone book and calling 10 or more different people or companies or government agencies before you finally figured out who could give you the information.
People made more phone calls and wrote more letters before the internet.
It really is quite amazing how much things have changed now. Often, I will be looking something up on the net and I will wonder how someone would have been able to find out this information before the internet.
