The original, oft-imitated, never-quite-replicated: "Beverly Hills, 90210" is the icon that truly launched the "rich teens and their drama" sub-genre. In 1990, when the show premiered, the TV landscape looked very different, and aside from a few older shows that were more family shows with teen characters, "teen TV" didn't really exist. Then, along came Kelly, Brenda, Dylan, Brandon, Donna, and all their friends, and all of a sudden, teen TV was all anyone could talk about. Over the course of 10 seasons, these teens dealt with standard-issue teen drama like love triangles and grades, along with more serious questions about addiction, sexual assault, and bigotry. It certainly had its moments of absolutely wild plotlines, but it remains a classic for a reason.
