Does anyone know what has happened to the Fox sitcom ROC. Has it been cancelled or was it merely pre-empted this week to promote MARTIN? Also, I am putting together a list of working class sitcoms currently on the four commercial networks. (This is obviously going to be a short list.) So far I have only THE SIMPSONS and ROSEANNE (as well as ROC, if is still alive.) Any suggestions? (To define what I mean by example, I would include THE HONEYMOONERS as a working class comedy, as well as the three shows listed above.)
