You would think that, but reality is that people keep coming back to Roseanne and Olbermann because they are brands that people recognize. It takes many years of paying dues to build personality brands as more and more people recognize a name.
@jmyrlefuller If there's one positive thing about Keith Olbermann, it's that the man has an absolute genius for getting himself fired within a very short time of getting himself hired, re-hired, re-re-hired, and so forth. He may yet set a record for being fired, re-hired, and re-hired at least as often as Zsa Zsa Gabor got married, divorced, and re-married, and re-divorced, and so forth.
