I grew also up without a television. That was no deliberate choice, my parents are orthodox christians. I was very creative in that period and I kinda miss that now :)
I did. No TV thru high school, minimal later, culminating in full-slate cable service, then dumped it all for nothing more than an occasional DVD. Have no idea how any TV-watchers get anything done, as I'm working (home chores included) flat-out 18 hours a day and feel I can barely keep up with life.
I grew up without a television - deliberate choice. My friends couldn't believe how much cool stuff I could get done because of this.
