Out of the Dark There Came a Spark.

For the dead fandom thing (which was a super interesting read btw!) Xena warrior princess, The shadow, a lot of the fleicher cartoons, the GLEE fandom, Tom and Jerry, Buffy (I mean, I still watch and love it, but I'd be hard pressed to see anyone else talking about it), The land of the lost, The partridge family (Sadly). Thats all I can think of off the top of my head, anyways
