Wasn't 90210 one of the first shows to deal with a lot of the stuff we (we being teens/preteens/kids of the 90s-or that age of any generation) had to deal with?
Personally, I learned a LOOT from that show! My parents were a bit, umm, overprotective. And didn't talk to me about stuff. So while everyone at school was getting into this stuff I was very confused. Luckily, 90210 straightened things out for me a bit!! LOL
(Kinda weird tho, huh?)
