Pleased by the news that Keith Olbermann is returning to television, a Little Rock resident checked to see if Current TV, which will carry Olbermann's new program, is available in Little Rock. A Current TV website gave the heartening news that the channel is available through Comcast in Little Rock as Channel 107. But when our man checked his own Comcast digital TV, he found there was nothing between Channel 105 and Channel 111. After fighting through phone trees, countless recorded messages, and exhausting waits for someone to answer, he finally found a live person at Comcast who said that even the huge number of channels in the customer's cable package were insufficient to win access to Current TV, which is one of a very few non-conservative news channels on American television. (Olbermann is one of a handful of non-conservative news commentators.) To get a cable package that includes Current TV, our man was told, would require his paying Comcast an extra $10 month. It would also require the customer to take his old digital box to a Comcast office and trade it for a new box. The mainstream media don't make it easy for moderate and liberal views to get on the air. Sean Hannity is around the world before Keith Olbermann is allowed to put his boots on.
