There are some TV shows that last for years and years, and when they finally go away, they're barely missed. And then there is the phenomenon of the TV show that dies quickly but leaves an indelible mark. Ten years ago, ABC fielded such a show: My So-Called Life, produced by the thirtysomething team of Edward Zwick and Marshall Herskovitz, premiered on Thursday, August 25, 1994 -- and was quickly reduced to ratings rubble by another new 8 p.m. series, NBC's Friends. But in 19 sublime episodes, Life left a lasting pop-culture legacy. Not only did it launch the careers of Claire Danes and Jared Leto, it defined the modern family drama -- and has influenced an entire generation of television writers. Says Greg Berlanti, the creator of The WB's Everwood and Jack & Bobby, ''It's the most painfully honest portrayal of adolescence ever on television.''
