The show still hasn't made a decision whether Apu will no longer appear on the show or if they'll attempt to take the character in another direction so that he's no longer offensive to some viewers.

But Azaria confirms that he will no longer voice Apu.

I guess my question is this: was there always outrage against the character and the show just ignored it or did Apu all of the sudden say or do something that caused all the fanfare? The show has been on forever and Apu has always been a part of it since season 1.
