I'm part of the generation that was born in the mid-late 80s and early 90s. Sitting in front of a computer or a TV was pretty much unheard of. The only exception would be weekend morning cartoons.
I used to live for Saturday morning cartoons! Now, IF they show them, they are generally pretty awful IMO.
We live in a neighborhood in which there aren't any other children (or, well, there is one family, but they aren't very social), so sometimes DD is in daycare on days she doesn't need to be to make sure she gets interaction/play with other children.
We live on a small road (two cars cannot pass each other and stay on the road) with a 35 MPH speed limit that people often drive 50+ MPH on, so my biggest worry about her playing outside by herself is getting in the road, not being seen by a driver and getting run over. My mother, on the other hand, is afraid she will be abducted.
DD often gets on the computer so she can find music to dance to and loves to plays games where she can draw and create (like the Barbie website has fashion designer games). But she also plays with her LPS toys, the Little People house, etc, and does a lot of imaginative play.
As for bday parties, mine aren't very structured, but I don't spend tons of time in planning since I'm lucky if I have two other kids show up...and those kids are cousins. (This year, I had three!) Granted, we don't really have the room for a party at home, so we've had parties elsewhere.
For DD's 1st and 2nd bdays, we had it at the local park/playground. The kids ran around and played until food was ready and/or we were ready for cake. Then more play on the playground. It was great the first year, but we have a summer bday, and it was just too hot to be outside the second year.
For her 3rd bday, Mom encouraged me to have her party at McDonald's. She had one of my brother's bdays there a long, looong time ago. There was a party coordinator who organized some games for the kids to play. For us, they roped off a too small section for us, every child got a soda and a frozen yogurt and an old happy meal toy. And for that, I was charged $70.
The next year, we had it at a place that is like a Chuck-E-Cheese. I paid $180 for a private room for an hour and a half, a few pizzas, sodas, chips, and tokens for the games. And two other children came.
Last year, for bday #5, I just said forget it....we're going to Disney! No party.
This year, no Disney...so party at the bowling alley. They played a couple of games (should have stuck with one) and had cake, pizza (provided by me) and chips and soda (provided by bowling alley). Everyone had fun, although still only 4 kids (was expecting at least 4 more...)
