'The Simpsons' to 'House': FOX's 25 best and most important shows of the last 25 years

The teen soap of the 1990s started out with a different title ("Class of Beverly Hills") and a fairly genteel tone, but soon enough we were getting stories about Brandon taking U4EA, Kelly and Dylan hooking up while Brenda was away for the summer, "Donna Martin graduates!" and more stories burned into the collective memory of Generation X. As FOX expanded to programming every night of the week, the original "90210" became a cornerstone of the network.
