4 Seasons deep, 8 episodes long, and it still had a larger impact than what most would expect. Were there tv shows before 90210? Of course. The premise of the shows values was set by the many "teenage drama" shows before it, but this show took it to another level. It showed a realistic portrayal of everyday teenage problems that everyone could relate too. The best part about it was anyone, from adults down to 5 year olds could watch it and get something out of it. The cast of Jason Priestley, Luke Perry, Shannen Doherty, Jennie Garth, Tori Spelling, and a plethora of others weren't only actors, but household names and teen idols. But that's the 90′s for you, real icons.
