Keith Olbermann and Current have parted ways, and not very amicably.
Current TV was way too amateur-looking to make any headway in the cable waters. I had hopes that having Keith meant they were preparing to up their game, but sadly it was not true. Their failure to promote, their many technical problems, their inability to upgrade to HD means that they'll continue to be media joke fodder as a network with viewership in the double digits. It's a good thing that Keith is free to move on to something else.
