Being born in the early 80s myself, I have to say the 90s was an awesome time to grow up. That decade, more than anything IMO, will be remembered for the rise of the Internet and how it ultimately made our world a much smaller place. Information could now be seeked in out ways just not possible before. I still to this day remember the first time I went online, and what I searched for (Orbital, Scottie Pippen). People who grow up today cannot understand the feeling of suddenly having access to all this information and media at your fingertips, whereas before you would buy a magazine just because it had a small note or picture of your favourite band/sports star.
And for me, growing up a basketball fan, the 90s were the start of the globalization of the game, and I got to grow up seeing the Bulls and Jordan plow through the league and become legends.
For the rest the 90s brought with it the massive rise of electronic dance music (Orbital, Prodigy, Chemical Brothers, Leftfield, Cassius, Daft Punk) and the whole club scene. And not coincidentally, videogames went from being kids play to something cool. Electronic dance music and videogames grew up together in the 90s, a bond forever forged with the controversial and edgy marketing of games such as WipEout (techno soundtrack, and marketing ads in magazines which depicted nosebleeds from playing, which was a straight on reference to drug use). Suddenly you could find clubs with PSOne stands inside, kids playing WipeOut while tripping on E.
Great tv series (Twin Peaks, X-Files) and games (the switch from 2D to 3D was an amazing time to be part of, and this era saw two of the greatest consoles ever in the SNES and PS1) that I still look back upon fondly.
So yeah, for me the 90s were awesome. It brought forth the internet, globalization, digital media (DVD's, MP3's), electronic dance music, clubbing, basketball and great movies and games who's influence is being felt today. For me that meant revolutionary times in the sense of making out your own identity in the way yourself saw fit. It brought freedom, experimentation, happyness and awareness. I wouldn't want to grow up in any other decade to be honest.
