But Murdoch was allowed to buy all the media he wants.

Who will control the New York Times?
Sources: Geffen made an offer for hedge fund's big stake.

So David Geffen (a LIBERAL ::gasp::) wanted to buy 19% of the New York Times. And was turned down. 19% isn't even a controlling share. But shameless pirate Rupert Murdoch keeps buying whatever he wants, Fox, Wall Street Journal, etc.
Sure.
Tell me again, how is our media supposedly so very very liberal?
