it means....?
What it means is a 1/3 of MSNBCs ratings (audience) are split between FOX and MSNBC, they shouldn't count. So not only are they split because the media company is BIASED, they only have a round 500k ratings...
I only watch MSNBC to hear olbermann bitch every night about how he hates FOX. funny how he was a sports anchor over at FOX before he was at MSNBC. Murdoch went on to personally fire olbermann because hes an starfish.
