Dumb Numbers

I don't quite believe this statistic. According to an article about in-elevator television and the move to live streaming news vs. time-delayed broadcasts, there's the following bit:

57% of Captivate viewers use the network as their primary source of news during the day

More than half of the people who watch the news during their elevator ride consume no other news throughout the day? Even though Captivate's streaming news comes from CNN and USA Today, that dismays me a little.

Can it be true?
